MatFun

Applies a function to the specified dimensions of a matrix

MATFUN Applies function to the specified dimensions of the matrix
A = MATFUN(FUN, MAT, DIM) applies the function specified by FUN to the dimensions DIM of the matrix MAT.
DIM is vector which maximum size is 3.

Example1:
A = rand(3,1000,1000);
% We want to compute the norm of the vector along the first dimension.
B = matfun(@norm, A, 1);
% B is a 1000x1000 matrix containing the norms of the vectors.

Example2:
A = rand(4,4,1000);
% We want apply the inverse function to all the 4x4 matrices
B = matfun(@inv, A, [1,2]);
% B is a 4x4x1000 matrix
