how to plot exponential function

hello! so i am kinda confused with how to change this to matlab code, because i've tried exp*(-1000*|t|) still not working

pls help me! thank you!

x(t)=exp(-1000|t|)

[madhan ravi]

syms t
x=exp(-1000*abs(t))
fplot(x)

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');

[madhan ravi]

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.

its working!!! thank you!!

Anytime :), make sure to accept the answer if it helped you

[JOHN GIL BILOLO]

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;
