Problem with columns and vectors

[s-soberh]

Hello
as in the Monte Carlo simulation in the help (step 7), the columns with the variable i are separated into vectors.
How can I just get the positive or negative values?

Example: From this column I only want the positive or negative values.

I use Mathcad Prime 4.0

You could also use a combination of "match" and "trim".
