I got stuck with the when trying to plot using ezplot

clc;
clear all;
close all;
syms x w

X = (sin(w))/w;
X1 = ifourier(X)
x  =  -10:0.01:10;
X1 = -(pi*heaviside(x - 1) - pi*heaviside(x + 1))/(2*pi);
figure (1)
ezplot (X1,[-10 10]);
title ('ezplot');
figure (2)
plot(x,X1);
title ('plot');

Hi, I'm new to Matlab since I want to plot the inverse Fourier transform of the signal X(ω) = sin(ω)/ ω using both plot and ezplot, I got the plot part but the ezplot keep giving the error that ' Input must be a character vector expression, function name, function handle, or INLINE object.' Please help

There are some mistakes in your code. Check the following code

clc;
clear all;
close all;
syms x w
X = (sin(w))/w;
X1 = ifourier(X);
x  =  -10:0.01:10;
X2 = -(pi*heaviside(x - 1) - pi*heaviside(x + 1))/(2*pi);
figure (1)
ezplot (X1,[-10 10]);
title ('ezplot');
figure (2)
plot(x,X2);
title ('plot');

Note, ezplot() is depreciated. It is better to replace it with fplot().

the problem ask that I need to use ezplot to plot so is there any ways?

[Ameer Hamza]

The code in my answe use ezplot(). Have you tried running it?

No Problem! I am glad to be of help!!!
