I suspect that if you apply > the > double operator to target, it will work okay. If you put two blocks of an element together, why don't they bond? The compiled library will throw an exception when it hits the complex arithmetic.

Not the answer you're looking for? You may also want the times operator, .*, rather than the mtimes operator, *, although they do the same thing with scalar arguments.
This often results in results that force you to worry about the actual computation rather than the mathematics; quite the opposite behavior. i am surprised though. –Brahadeesh Mar 21 '11 at 2:14 add a comment| up vote 4 down vote The imread function returns a matrix of uint8 elements for grayscale bmp images. laconic wrote: > > > % error part of the code % > target=imread('lena.jpg'); > f=target(:,:,1); > for x=1:32 > for y=1:32 > rt=sqrt((x-x1)^2+(y-y1)^2+z^2); > temp=f(x,y)*exp(-(i*7.33*rt))/32; %% error is here > Play games and win prizes!

The matlab code doesn't do any I/O operations - that is all handled by the c++ natively and then passed into the matlab functions.
