hey there,
this is my code every thing works good with no errors.
but show me some charts az empty, how to fix
is it related to : the Equation doesnt have real value?
code :
syms t
x1 = @(t) (exp(-t) * heaviside(t));
X_w = fourier(x1(t))
h = @(t) heaviside(t + 1) - heaviside(t - 1);
H_w = fourier(h(t))
Y_w = (X_w)*(H_w)
y1 = ifourier(Y_w)
subplot(2, 4, 1);
fplot(X_w, [0, 2*pi]);
grid on;
xlabel("w");
ylabel("X(w)");
subplot(2, 4, 2);
fplot(H_w);
grid on;
xlabel("w");
ylabel("H(w)");
subplot(2, 4, 3);
fplot(Y_w);
grid on;
xlabel("w");
ylabel("Y1(w)");
subplot(2, 4, 4);
fplot(y1);
grid on;
xlabel("t");
ylabel("y1(t)");

All parts other than y1 are complex, so the real or imaginary part must be specified.
eg. real(X_w)
