Hi, I have an array, let's say
M=
1 1 0
1 2 0
1 3 1
2 1 0
2 2 1
2 3 1
and I would like to create a new array only with the case for which the value of the third column equals 1. Thus
N=
1 3 1
2 2 1
2 3 1

Try this:
M=[...
1 1 0
1 2 0
1 3 1
2 1 0
2 2 1
2 3 1]
rowsToExtract = M(:,3)==1;
N = M(rowsToExtract,:)
