i have a multidimensional matrix (146x146x144) that i want to reshape (144x21316). the command reshape works "vertically", how i can reshape "horizontally" ( every rows next to another)

reshape(permute(matrix, [2, 1, 3]), 144, []).'

for examplei have a matrix
[ 1 1 1 1 1 1 1 1 1
2 2 2 2 2 2 2 2 2
3 3 3 3 3 3 3 3 3 3]
That has one too many 3's in the last row. Correcting that problem:
A = [ 1 1 1 1 1 1 1 1 1;
2 2 2 2 2 2 2 2 2;
3 3 3 3 3 3 3 3 3];
P = reshape(A.', 1, [])
If your A array is actually a 3-dimensional (or generally N-dimensional for N > 2) you're going to want to use permute instead of the .' operator.
P2 = reshape(permute(A, [2 1]), 1, [])
To ask a similar question that madhan ravi did, for this specific array:
B = reshape(1:24, [2 3 4])
What exactly do you want the result of reshaping B to be? Give us the explicit command to create Breshaped:
Breshaped = [ % Fill in numbers here]
Once we know what you want Breshaped to be we can help you write the command to create it.
