printing complex
I am opening a file and trying to print cpomples roots but only showing real parts on the file given code below here s is calculated above by a diferent program but my problem is to get real and imaginary on the file output named newresults.dat fid = fopen('Newresults.dat','w'); s=[T0 T1 T2 T3]; r=roots(s);... 28 Mar 2010 08:58

Looking for a Mex-file approach to speed up the computation of a partial-FFT algorithm
The Matlab build-in function "fft" is a highly efficient algorithm for fast implementation of the Fourier transform. However, in some situations I do not need the calculate the full-point FFTs every time. Suppose I only need to calculate a subset of outputs, I have to develop a partial FFT (i.e. fractional FFT, or prun... 28 Mar 2010 03:36

Is it possible to display Arabic text using the Matlab Editor?
I'd like to input some Arabic text into a Matlab m file using the Matlab Editor. However, whenever I type in Arabic and save the file and then open it again, the Arabic text that I saved earlier turns into a couple of question marks (????).
