Hi,
I an array (phases) with two vector of the same lenght. I need to compare the two vectors under the following conditios:
phases(:,1) phases(:, 2)
1................................. 2
1................................. 2
1................................. 2
2................................. 2
2................................. 2
2................................. 1
2................................. 1
2................................. 1
2................................. 1
1................................. 1
1................................. 1
1................................. 1
condition 1: I want to know the number of times phases(:,1) and phases(:, 2) are both 2 in the same row. In this case, there are 2 times.
condition 2: I want to know the number of times phases(:, 2) is equals to 2 when phases(:,1) is equals to 1 in the same row. In this case, there are 3 times.
condition 3: I want to know the number of times phases(:, 1) is equals to 2 when phases(:, 2) is equals to 1 in the same row. In this case, there are 4 times.
Thank you!

The following code counts the number of rows which meet the condition 2.
nnz(phases(:,2) == 2 & phases(:,1) == 1)
hope this helps.
