MATLAB: How to run this code with some values of k

continuous signalfourier transformintegersignals and systems

Hello!
I have this:
I run this code:
syms t
k = 0;
x(t) = 3*dirac(t-3*k*pi)+2*dirac(t-3*k*pi-pi)+dirac(t-3*k*pi-2*pi)
f = abs(fourier(x));
a = angle(fourier(x));
subplot(2,1,1)
fplot(f, [-5 5])
grid on
ylabel('Magnitude')
subplot(2,1,2)
fplot(a, [-2 2])
grid on
ylabel('Phase')
xlabel('Angular frequency(ω)')
How to choose some values of k, which is an integer, for example from -5 to 5?

%true
syms t k
F= @(t,k) 3*dirac(t-3*k*pi)+2*dirac(t-3*k*pi-pi)+dirac(t-3*k*pi-2*pi)
f = abs(fourier(F,t,k));
a = angle(fourier(F,t,k));
subplot(2,1,1)
fplot(f,[-5 5])
grid on
ylabel('Magnitude')
subplot(2,1,2)
fplot(a,[-5 5])
grid on 
ylabel('Phase')
xlabel('Angular frequency(ω)')
Try the above
