Hi, I have two matrices like below:
I want to search when the 2nd column equals 0 on either matrix and make a new matrix that shows the 0 values along with its paired column 1 values. I also want to tag it to know from which matrix it came from.
Thank you! I am new to conditional statements.

Where M1 and M2 are your matrices:
idx1 = M1(:,2) == 0;
idx2 = M2(:,2) == 0;
tags = repelem([1; 2],[nnz(idx1) nnz(idx2)]);
result = [[M1(idx1,:); M2(idx2,:)] tags]
