Convert matrix size from 1xmxn to mxn

I want to compare two matrices. One's size is mxn and the other matrix size 1xmxn. How can I convert 1xmxn to mxn??

Answer 1

[Andrei Bobrov]

Z =  randi(250,1,3,4); % your matrix

one way

out = squeeze(Z)';

other

out = permute(Z,[3 2 1]);

or

out = reshape(Z,size(Z,2),[])';

Googled really long on this! Thanks!

size(A)=1xMxN matrix. Unable to then imagsc(A(jpos,:,:))

error(using image Color data must be an m-by-n-by-3 or m-by-n matrix.)

Solved by:

Qi=squeeze(A(jpos,:,:));
imagesc(Qi);
% Squeeze used to convert the resulting 1xMxN matrix into a MxN matrix

Answer 2

Just adding some context to previous answer by Andrei Bobrov. Basic idea is to convert 1 x m x n matrix into m x n x 1 as matlab omits last dimension if it is 1. Therefore the method i prefer is:

NewMat=sqeeze(Z)';

Whereas other two functions does the same thing.
