Hello!
With an array like this:
A= 4 2 3
1 6 5
1 2 9
5 2 2
1 2 6
I would like to have an array with (for example) column 3 less than 5. I know that sortrows(A,3) can get the rows in order, but what is the (logical?) test to eliminate these rows?
Thanks!
Doug

To eliminate the rows with the value of column 3 less than 5, keep those with the value of column 3 greater than or equal to 5:
A = A(A(:,3) >= 5, :)
similarly:
A(A(:,3) < 5, :) = []
will both produce:
A =
1 6 5
1 2 9
1 2 6
Is this what you want to do?
