A = [
0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 1 0 0 0 1 1 1 0 0 ;
0 0 0 1 1 0 0 1 1 1 1 0 1 1 0 0 0 1 0 0 1 0 1 0 0 ;
0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 0 0 ;
0 0 0 0 0 1 0 1 1 1 1 1 1 1 0 0 0 1 0 0 0 1 1 0 0 ;
0 0 0 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 1 1 1 0 0];
Can we only extract existing values of 1 from many rows? For examples the result is:
Result = [
0 0 0 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 0 0 1 0 0];
Only one row. Without looping and IF.
*note: The matrix A is only for display. We can copy and paste, but need to adjust the matrix.
