MATLABprovides flexible, two-way integration with many programming languages, including Python. This allows different teams to work together and use MATLAB algorithms within production software and IT systems. This webinar will cover how to call MATLAB from Python and how to call Python libraries from MATLAB.

I recently spent a couple of weeks without an individual MATLAB license at work. Of course, I had the chance to use workstations with shared licenses in the office to continue working in Model-Based software development. For that kind of activity, you can't just go around the license problem.

In each entry, I will share a simple but practical example of how to do a certain task with MATLAB, but using Python instead. Probably some of the code can be improved, but I think it can be useful to see these examples if you are a beginner like me.

I think this is important since Python opens the possibilities for individuals and companies that cannot afford to buy an expensive MATLAB license, or are already using MATLAB for scientific computing, in which case it can be easily replaced with Python, cutting down the license costs.

MATLAB is still being used widely, especially in the Automotive and Aerospace industries, but the usage of Python has grown dramatically in many different sectors, since it can be used for many other things - like I said, general-purpose.

Extracting and doing the first-level analysis of data from large log files is a very common use case of MATLAB in automotive testing environments - at least from what I've seen in three different large companies in Europe. It could be seen as a mundane activity, but it is not straightforward if the files you have are in different formats. Also, it might be something you need to do very frequently.

For this series of posts, I will look at the tasks I learned to do with Python once the data was available in some kind of universal text encoding. For instance a CSV file or an ASCII file. This is not always obvious, and there were many cases in which I needed to convert VECTOR CAN log files or other ASAM standard formats to text, or use some kind of API to be able to work with them in Python or MATLAB. But that will be part of another article later on.

First of all: this will not be a Python course. I am assuming you have already some basic understanding and want to see some basic examples of how to use it. You can learn the basics very quickly with tons of free tutorials and courses out there.

I followed the Scientific Computing with Python Certification on FreeCodeCamp.org a while ago, and it was great to grab the basics. There are also great resources like Real Python and Geeks for Geeks, and many courses on Udemy, Coursera, EdX, DataCamp, and others.

If you are coming from MATLAB and want to start using Python, you probably want some kind of user interface or IDE (Integrated Development Environment) to work with. There is no unique or best answer here, so I will just tell you about the ones I have tried.

The first thing is, of course, to download and install Python 3 itself (Python 2 is already in an End-of-Life stage and will no longer be supported by new libraries). Then, you can download and install one of the following IDEs:

Personally, I prefer to use VS Code since it allows me to work also on other types of programming projects in the same environment, for example when working with Arduino. However, the code examples I will share will work no matter the IDE you are using.

If you download the file, you'll notice that there are missing values on each variable (CAN signal). The good news is that there is a common time vector for the different channels - although the data might have been transferred at different rates over CAN.

I needed to represent data containing information about speed, in rpm, and torque, in Nm. And I wanted to visualize both against the same time scale, in order to understand what happened during the test I am looking at.

This is why I created a tiled layout. I could have used subplots instead, and the results would have been very similar. Or I could have plotted both speeds and rpm against a single abscissa, but using two different y axes using yyaxis right.

In this case, we are dealing with data from a text file, so it is a common practice to use the library called Pandas. It can be slow for doing complex computations or handling large datasets, but there are some workarounds.

In Python, we have to get used to working with methods other than functions. This will allow us to do different things with the variables we are working with, depending on what type of object (class) they are.

For instance, we loaded the data from the file as a dataframe object that we called df (we could have called it anything if we wanted, but df is more self-explanatory and common practice). Then, to extract the non-empty values we use the . notation to access the notnull() method of the dataframe class.

This is different from the function-based approach that I used in the MATLAB script above, where I used the isnan function, and it would have worked on either a double array, a scalar, a matrix or a multidimensional array.

MATLAB is specific for matrix computations, so it relies heavily on functions, whereas Python has specific libraries for different purposes, and they use both functions and methods to accomplish some tasks. There are also some built-in functions in Python

Next, we create the figure and plot the data. We first need to specify the figure size, otherwise, the default figure dimensions will be too small. In this case, we are using subplots to obtain the following result:

Granted, the Python plot needs a bit more manual formatting to have the same look as the MATLAB one. But this is not really an issue once you know what you need to change to get the format you want. You can set the defaults for creating figures on the top of your script, or make a function that does the formatting for new figures.

If you have trouble getting some details to work, you can just google your answer. The amount of Python users is huge and growing, so it is very likely you will find someone already asked a similar question online.

For instance, I was having a hard time getting the axes titles to show correctly, and there was a Stackoverflow thread solving exactly the same issue - turns out you need to add plt.tight_layout() for the figure to be padded correctly. Just part of the learning curve.

This post was a bit longer than the others, being the introduction of the series, but I hope you found it helpful or at least interesting. Over the next weeks, I will be sharing other example codes, highlighting the differences between MATLAB and Python, and showing also the things I struggled with. I hope you are motivated to learn Python, as I am, and this can be an incentive to try it on your own.

I installed MATLAB R2021A and I found that when creating the matlab.desktop it generated problems, and it was that two icons appeared in the dock, I put MATLAB in favorites but when I opened it, it did not open from there, if not it opened in another.

Finally, I managed to solve it, in many places I saw that I had to add this StartupWMClass = com-mathworks-util-PostVMInit in /usr/share/applications/matlab.desktop but it did not help me, finally what I did was add that line but different

but one thing was missing to select the correct image of the icon, since generally one finds that they download it from the internet, but this generates an error, so it is better to choose the one that comes in the download files, since it seems that two icons appear because there are errors in the matlab.desktop that makes it impossible to open from there

i am a engineering student and i have to do a lot of numerical processing, plots, simulations etc. The tool that i use currently is Matlab. I use it in my university computers for most of my assignments. However, i want to know what are the free options available.

i have done some research and many have said that python is a worthy replacement for matlab in various scenarios. i want to know how to do all this with python. i am using a mac so how do i install the different python packages. what are those packages? is it really a viable alternative? what are the things i can and cannot do using this python setup?

I've done exactly this (replace Matlab with Python) about 2 years ago and haven't looked back. The broadcasting in Python, more intuitive memory model and other Numpy advantages make numerical work a complete pleasure. Plus with f2py, cython it is incredibly easy to put inner loops in another language. This is a good place to start - other impressive pages to provide motiviation are PerformancePython and ParallelProgramming. Be sure to understand Pythons "variable is a reference to an object" semantics... after that adjustment everything is plain sailing. One of the coolest things that beats matlab is in 2 lines I run over 8 cores... p = Pool(8); res = p.map(analysis_function,list_of_data) - MATLAB parallels toolboxes are so expensive I've yet to see a University that actually has them.

Then, by all means, use Matlab. Otherwise, if you have data structures other than matrices, want an open-source option that allows you to deliver solutions without worrying about licenses, and need to build on platforms that mathworks does not support; then, go with Python.
