PM and FM signal

Hello, I want to know if there is any problem with my code of phase modulated signal and how can I perform frequency modulated signal direct from this PM signal? Theoretically, I can use an integral for this PM signal and I can have immediately FM signal, but I don't know how to express that in Matlab. Thanks for your help.
fa = 3e5; %sampling frequency
delp = pi; %phasehub
fo1 = 15000; %carrier frequency
tq = -1e-2:0.0001:1e-2;
vq = cos(2*pi*1500*tq); %Source Signal
vp = cos(2*pi*fo1*tq + delp*vq); %pm signal
plot(tq,vp);
title('Phasen signal');
xlabel('time');
ylabel('Amplitude');

For phase modulation (any modulation) you need two signals, a carrier signal, and input modulation signal, the output will modulated wave.
tq Time starts in minus...?
Clarify?
