Try imfilter() function.
B = imfilter(A,h) filters the multidimensional array A with the multidimensional filter h and returns the result in B.
Refer to the following documentation link on imfilter function:

Hope this helps.

The 'laplacian' and laplacian-of-gaussian ('log') filters are both high-pass filters. The laplacian of gaussian filter may help reduce the response to image noise.
