a=cos(mu);
x=(1000./Ve.^2).*(1./a);
            %  ^---^-----missed dots
y= P.^(x.^(3/2));
Gives:
>> x
x =
   -0.0763
    0.1702
    0.4502
    0.1322
    0.0720
   -0.0729
>> y
y =
   0.9982 - 0.0596i
   1.2200 + 0.0000i
   2.3740 + 0.0000i
   1.1549 + 0.0000i
   1.0595 + 0.0000i
   0.9980 - 0.0633i
