MATLAB: Convert a matrix with some zero elments to an array with non-zero elments

logical indexing

Hi all
I have a matrix 'A' including some elments equal to zero. i want to make an array 'B' with the non-zero elements of A . for example:
A = [46 0  23;10 73 0; 0  57  13]
B=[46  23  10  73   57  13]
 How can I write this program?
 Thanks

Best Answer

AT = A'
B = AT(logical(AT))'
A =
    46     0    23
    10    73     0
     0    57    13
AT =
    46    10     0
     0    73    57
    23     0    13
B =
    46    23    10    73    57    13
