Thanks for any help! mkdir(image_name,'image_color') for k = 1 : n... 23 Jun 2010 10:36

Correct use of fftshift and ifftshift at inpu tto fft and ifft
I've seen discussion here of the correct use of MATLAB's fftshift() function. I'd like to verify my interpretation, and to ask what are the effects when people do not use it correctly. Basically, MATLAB implements an fft (as do other sets of functions) whose results AND inputs are ordered (for an array of N eleme... 23 Jun 2010 13:57

Simulating a non-linear system with embedded matlab function in simulink
Hello together, i'm trying to simulate a non-linear model consisting of three differential equations in simulink. I'm using a very simple structure with step-block, embedded-Matlab-function, integrator and Scope. This simulation returns the following error: Embedded MATLAB Interface Error: Call to MATLAB ... 23 Jun 2010 06:13
