I have a matrix with two columns. I want to create a new one that only contains the rows without a 0 in the second column.

I have a matrix, A, that looks as follows. My goal is to have a new one, B, that is only made of the rows that do NOT have a zero in the second column.

A = [7.36  0;
    7.37  0;
    7.38  2;
    7.39  0;
    7.45  1;    
    7.81  5;
    7.94  6;
    7.98  0]

B = [7.38  2;
     7.45  1;
     7.81  5;
     7.94  6]
