# MATLAB: I am trying to create two vectors out of one,x, where one will contain all the positive elements and the other all the negative elements.

loopsvector

%this program creates vectors N and P out of x%N will contain negative elements and P the positive elementsx=[-3.5 -5 6.2 11 0 8.1 -9 0 3 -1 3 2.5];for k=length(x);    if x>=0        k=x        P(k)=k    else x<0        N(k)=k    endendPN

x=[-3.5 -5 6.2 11 0 8.1 -9 0 3 -1 3 2.5];P = x(x >= 0);N = x(x < 0);
