Fast Convolution in matlab

Are there any fast alternatives for conv2 function present in matlab? I found one on Rob Fergus's site on NYU, but it seems to be built for Linux machines. Any version for windows?

UPDATE Is there any way to transform everything into frequency domain and do this? or am I totally wrong on this?

FFTs are often used to implement fast convolutions (a convolution is just a product in the frequency domain), but as far as I know this only starts to pay off when the filters are large enough. How large they have to be probably depends on the problem setting and the hardware.

I think Mathew Zeiler's code is for Matlab. Try compiling it in a windows machine http://t.co/qXNudRv6dD
