Re: MATLAB R2018a [PC] [x86] With Serial Download Pc

Since MATLAB R2018a, complex-valued matrices are stored internally as a single data block, with the real and imaginary component of each matrix element stored next to each other -- they call this "interleaved complex". (Previously such matrices had two data blocks, one for all real components, one for all imaginary components -- "separate complex".)
MATLAB has a function typecast, which casts an array to a different type without copying data. It can be used, for example, to cast an array with 16 8-bit values to an array with 2 double floats. It does this without copying the data, the bit pattern is re-interpreted as the new type.
I tried creating a MEX-file that does this, but I don't see how to create a new array that references the data in the input array. This MEX-file works, but causes MATLAB to crash when clearing variables, because there are two arrays that reference the same data without them realizing that they share data (i.e. the reference count is not incremented).
Seeing how MATLAB allows us to call python libraries, we can perform these sort of manipulations within python, and only bring the data back into MATLAB when we reach a stage where proceeding in python is impossible or undesired. Depending on when this stage might be, this idea could be either a valid approach, or a completely useless suggestion.
While experimenting with this, I came to realize that there's much difficulty1 involved in transferring non-scalar complex data from MATLAB to Python and back (just compare the MATLAB output for np.asarray(1+1i) vs np.asarray([1+1i, 1+1i])). Possibly, the reason for this is the limited support for complex non-ndarray arrays in python.
If you (as opposed to me) know what to do with memoryview objects (i.e. the content of the data field of the ndarray objects) - you could get a pointer and perhaps pass this on to C to get some useful results.
Using typcast for other data types seems that to be doubtful. I can (and probably should) assume that MATLAB has used some compiler tricks to prevent undefined behavior, otherwise when we are accessing a data element if MATLAB hasn't copied it byte by byte then it results in an undefined behavior.(Note that anyway casting between compatible types like int32 and uint32 and also casting any type to c++ char type have well defined behavior). Moreover it requires that all mex file to be compiled with the proper option to disable strict aliasing. But we currently have plenty of compiled mex files that if we send to it a result of typecast it leads to an undefined behavior. So use of typecast should be restricted as much as possible.
I recently installed MATLAB R2018a in my artix linux (runit). I can launch matlab from the location where the launcher is, i.e.,/usr/local/MATLAB/R2018a/bin, but if I try to launch it from another location I can't. So I tried to append the mentioned directory to PATH with different methods:
You are right! I thought it was An error about stamps.turns out it is a matlab library problem ,I go search on matlab forum you recommended and finally fix it .Thnak you so much for giving me advice!!!
Hi. I installed Matlab R2017b (downloaded from the MathWorks website) and it worked fine for a while.
But now, whenever I try to start it, the program crashes with a "Segmentation violation detected" message.
I looked into the Arch Wiki and there is a section on that error message, but it seems to be outdated - it recommends to install ncurses5 (but newer versions of Matlab should be compatible with ncurses6). I gave ncurses5 a try and that didn't fix the problem.
Reinstalling Matlab hasn't fixed anything either (this time I was only able to install in silent mode with root privileges).
- switched between nouveau and nvidia graphics drivers
- tried both software and hardware opengl (Matlab often switches back to Software opengl)
- tried openjdk-8 and openjdk-9
- disabled/re-enabled Java 2D opengl rendering
- replaced the libstdc++.so.6 link with a symbolic link to /usr/lib/libstdc++.so.6 (a bug that has apparently been fixed since Matlab R2016b)

A big question is..... have you managed to get simulink to work with arduino in any particular way .... such as via one of their provided examples? Simulink has at least 1 example. You should mention if you managed to get that (or any) example working. This should be automatically mentioned..... because nobody can read your mind and know what you've done before (or not) with simulink.
From the forum topic you referenced, it sounds like you want to use FAST v7 due to its linearization capability. But it was not possible in FAST v7 to perform a linearization analysis when using the Simulink-FAST v7 interface anyway. Perhaps you could change your process so that you use the FAST v7 executable (without the MATLAB/Simulink interface) to generate the linear state-space models and use the Simulink-FAST v8 interface to run nonlinear time-domain simulations?
As you proposed, I have done linearization in the FAST v7 with platform DOFs. Now my plan is to design an LQR for FAST v8 using the state-space system of equations I have obtained from linearization in the FAST v7.
Afterwards, to test the system in simulink, I apply unit step at the wind input for linear system and obtained the following output pattern. Rest of the control inputs are zero.
Scale for output_1 for y axis is from 0-300.
Some thing went wrong with the linearization process. Please advice how to solve the issue.

When you eliminate the generator-azimuth state from the linear state-space model, you should eliminate the corresponding columns from the A and C matrices and you should eliminate the rows of the A and B matrices associated with the first derivative of the generator-azimuth state (i.e. the generator speed). Did you do that?
Dear all,
recompiling the FAST7 sFunction in Matlab R2018 solves the issue mentioned in the first post (unfortunately full quote not possible). Matlabs Fortran API changed slightly and the missing symbols above are called with some version numbers. The correct way to implement the changes would be to include the fintrf.h in FASTGateway.f90. As I was unable to get this to work, I adjusted FASTGateway.f90 to call the functions directly:
The version given to the find_package() directive is the Matlabversion, which should not be confused with the Matlab release name(e.g. R2023b).The matlab_get_version_from_release_name() andmatlab_get_release_name_from_version() provide a mappingbetween the release name and the version.
A Matlab scripts can be added to the set of tests using thematlab_add_unit_test(). By default, the Matlab unit test frameworkwill be used (>= 2013a) to run this script, but regular .m filesreturning an exit code can be used as well (0 indicating a success).
By default, every symbols inside a MEXfile defined with the command matlab_add_mex() have hiddenvisibility, except for the entry point. This is the default behavior ofthe MEX compiler, which lowers the risk of symbol collision between thelibraries shipped with Matlab, and the libraries to which the MEX file islinking to. This is also the default on Windows platforms.
However, this is not sufficient in certain case, where for instance yourMEX file is linking against libraries that are already loaded by Matlab,even if those libraries have different SONAMES.A possible solution is to hide the symbols of the libraries to which theMEX target is linking to. This can be achieved in GNU GCC compilers withthe linker option -Wl,--exclude-libs,ALL.
This function parses the Windows registry and founds the Matlab versions thatare installed. The found versions are returned in matlab_versions.Set win64 to TRUE if the 64 bit version of Matlab should be looked forThe returned list contains all versions underHKLM\\SOFTWARE\\Mathworks\\MATLAB andHKLM\\SOFTWARE\\Mathworks\\MATLAB Runtime or an empty list in case anerror occurred (or nothing found).
Populates the Matlab root with valid versions of Matlab orMatlab Runtime (MCR).The returned matlab_roots is organized in triplets(type,version_number,matlab_root_path), where typeindicates either MATLAB or MCR.
The function expects one Matlab test script file to be given.In the case NO_UNITTEST_FRAMEWORK is given, the unittest script fileshould contain the script to be run, plus an exit command with the exitvalue. This exit value will be passed to the ctest framework (0 success,non 0 failure). Additional arguments accepted by add_test() can bepassed through TEST_ARGS (eg. CONFIGURATION ...).
