sanjay,
The most probable cause might be that you invoked the function using inappropriate parameters. The function allocate a 3D matrix of size [size(im,1)+maxR, size(im,2)+maxR, maxR-minR+1], where minR and maxR are the minimal and maximal radii of circles you want to detect, respectively. You may want to check if the size of your input image or the values of minR and maxR are really huge.

hi, i've ran this code and it works. i wonder which part of the code display as accumulation array? can you pls guide me how to create the accumulation array from this code in order to generate the output figure of hough transform accumulation array?

i used the houhcircles function. it says 'out of memory' for my test images; but it worked for very small binary images; please help
