How to delete zeros from matrix in MATLAB?

Question

Here is my problem:

I have a nxn matrix in matlab. I want to delete all the zeros of this matrix and put the rows of it in vectors. For n=4

Answer 1

Convert to a cell array such that you have a cell for each row and then use nonzeros for each cell, that deletes zeros and finally store them into separate variables.

Code

nzv =cellfun(@(x) nonzeros(x),mat2cell(A,ones(1,size(A,1)),size(A,2)),'uni',0)
[v1,v2,v3,v4] = nzv{:}
