I have somewhat of a confusing problem that I need help with. I am going to explain it the best that I can, so here goes. I have two column vectors, one is Cp the others is Cf. The Cp column has positive values and some negative values. I basically need to take the rows in the Cp column that are negative and make the same rows of Cf negative. For example:
Then the new column vector would be:
Basically making any negative row in Cp, negative in Cf.
Is there any easy way to do this? Any help is much appreciated.
