still not working:(
here is my full code
clc
clear all
close all
syms t
x=exp*(-1000*abs(t));
fplot(x);
y=fft(x);
figure, plot(t, abs(y)), title('Amplitude');
figure, plot(t, angle(y)), title('Phase');

Just try the below code by copying and pasting:
t=linspace(0,1,1000);
x=exp(-1000.*abs(t));
y=fft(x);
figure, plot(t, abs(y)), title('Amplitude');
figure, plot(t, angle(y)), title('Phase');
Note: when the argument grows towards negative the result tends to zero much faster because the growth is exponential.

t=linspace(0,30,5000);
x=exp(-2000.*abs(t));
y=fft(x);
xlabel('chito');
ylabel('loko');
plot(t, abs(y),'g--'), title('Amplitude tsamba lang');
plot(t, angle(y),'g--'), title('Exponential kunwari');
grid;
