How to play .avi in gui axes?
|
| |
I was playing around with GUIs, and I am stumped on something. I have a .avi file and wanted to play it in an axes in my GUI, how could I go about this with a loop? I have read up on the funcitons like movie(m) and getframe, but this has only confused me more. Any help is appreciated.

xcorr functional equivalent for linear-cirlcular cross-correlation?
|
| |
Hello, I'm trying to generate an estimate of the cross-correlation function for 2 time series. One time series is linear (domain -Inf - Inf) and the other is azimuthal (domain 0 - 2pi). If both functions were linear, I would simply use xcorr and be done. But here I can't do that. I've searched this site and found the (very useful) Circular Statistics Toolbox which has a function called "circ_corrcl" which computes the correlation coefficient between a vector of samples representing a linear random variable and a vector of samples representing a circular random variable. However, this function only gives one correlation coefficient value and one p-value as output.... more »

Write a function q1 10a that receives an integer n and returns n/2 if n was even and 3n + 1 if n was odd. To test if a number is an integer it is convenient to use the MATLAB function floor( ) which returns the largest integer smaller than the input number. For example floor(4.9) = 4 and floor(-1.1)=-2 and floor(15)=15. (Try this out!)... more »

OK so here goes my problem. I have spent ageeeess on this! Any help would be soo appreciated! Even if you can point out where I'm wrong..! Question: Solve the following system of equations by using Newton's method by implementing it in Matlab: f1 = 4 - 8*x1 + 4*x2 - 2*(x1)^3 = 0 f2 = 1 - 4*x1 + 3*x2 + (x2)^2 = 0... more »

isfield sub-fields question and loading field without switch statement
|
| |
Hi all, Two easy questions for you that I could not find an answer to: 1) I am sorting data into several sub-fields, such as A.B.C.D1 through A.B.C.D5 Now if I want to load A.B.C.D4 I need to use isfield to check if it exists first (I want to avoid all red text errors!). Is there an easier way to do this rather than use isfield 4 times for A, then A.B, then A.B.C and then A.B.C.D4?... more »
