I have a 3-dimensional array A which has 450 rows,210 coulms, 4 layers. I want to make a regression between A(450,210,1) and A(450,210,3), A(450,210,2) and A(450,210,4). For that I need to convert the array to 4 vecotrs. I don't know how to do that. I tried Reshape function but couldn't get what I want. Any help is appericiated.

A = rand(450,210,4);
EDIT
% Switch 2nd dim with 1st
A = permute(A,[2,1,3]);
% Reshape into vector each layer
A = reshape(A,450*210,4)
Each column now is the vectorized layer.

Type the following at the MATLAB command line prompt:
mex -setup
Then press Enter
Then enter the number of a C compiler such as lcc
Then press Enter again
Then try running mtimesx again.
