how to get a m-by-n matrix from grayscale image?
I have a grayscale *.bmp image and I want to make some wavelet operations on it, so I need it in matrix dimensions m-by-n. But when I read the image using the command imread(), matlab puts it in m-by-n-by-3 matrix. I have already tried using the command rgb2ind() but without luck, because it darkens the picture totally... 14 Jun 2010 10:38

? why cannot get LS soln with mini norm
Hi: I tried the following algorithm to see if I can get min norm LS soln for solving min f, f = 0.5*norm( A*x-b ), A is m-by-n and m < n. But the algorithm did not converge to the min norm LS soln. Does anyone know what's wrong? The algorithm used is: x(k+1) = x(k)-pinv(A)*f(k) The a... 14 Jun 2010 05:09

i have question about simulink (error calculation block)
At error calculation block in simulink blockset i don't understand received delay and computation delay respectively. because of my inexperience...so i have faced with difficulty. how i let the value computation delay? i heard that computation delay is needed only if frame-size simulation. Is it right? i hope ... 14 Jun 2010 04:05
