Matrix split in vector

Hello everyone! I need a little help, I'm at the beginning and I would like to create a function that receives a matrix with positive elements (0 included) and returns in a vector line by line the elements of the matrix without zeros. A little help, please?

ex: A = [1 2 0 3; 0 0 4 5; 6 0 7 8]

newA= [1, 2, 3, 4, 5, 6, 7, 8]

Answer 1

>> B = nonzeros(A.')
B =
   1
   2
   3
   4
   5
   6
   7
   8

and if i want B to be in row?

I have something like this:

function [values] = ceva(A)

B = A(A>0)

values = B';

endfunction

when i insert A, only display B = columne

edit: i fix it

"and if i want B to be in row?"

iwant = A(A>0)

If you want in the order you have given.

A = A' ;
iwant = A(A>0)
