3D volume to 2D matrix conversion

I have a 3D matrix of size 20*22*815 . What is the way that i can generate 2D matrix of 815 rows and 440(20*22) columns

Answer 1

[Matt J]

A=permute(yourMatrix,[3,1,2]);
A=A(:,:);

another possibility:

 A = rand(20,22,815); % your matrix
 B = reshape(A,440,815)';

The output of this code is equal to Matt's answer.

you can also use B=reshape(A,815,440) without using transpose, then B will be a 815*440 matrix, but the arrangement of data will be different. This is up to you what kind of arrangement you want.
