A = 942;
f0 = 19;
w0_1 = 38*pi;
Q_1 = -0.9426;
Q_2 = -0.1678;
t = 0:0.1:5;
cosfn1 = A*cos(2*pi*f0*t + Q_1);

For a cod segment above, I get an error as "Subscript indices must either be real positive integers or logicals." And this points tthe cosfn1. Why do I get such an error? Thanks for your help
