From: Ankit Goyal on 24 Jun 2010 06:11 hi Steve convmtx2 takes a filter (in the form of a 2-D matrix) and returns to you a convolution matrix. This matrix can be used in a matrix / vector multiply to perform 2-D convolution. I have image in stack form in 3D I want a convmtx3 like function which will takes a filter (in form of a 3-D matrix) and returns us a convolution matrix which can be further used to perform 3D convolution. I think make myself clear and what typr of function i am expecting. Please help me Steve. I am looking forward for it. Its very urgent. Thanks in advance
