syms t w
X = 1/(1+(1i.*w));
subplot(3,1,1)
ezplot(X,[-9 9]);

%inverse Fourier transform
X1 =ifourier(X,t);
subplot(3,1,2)
ezplot(X1,[-5 5]);
title('inverse transform');
%Fourier Transform
X2 =fourier(X1,w);
subplot(3,1,3)
fplot(X2,[-5 5]);
title('fourier transform');

Since ‘X’ and ‘X2’ are purely imaginary, it is necessary to specify that in the ezplot calls. In MATLAB, imaginary values and imaginary parts of complex values do not plot.
Try this —
syms t w
X = 1/(1+(1i.*w));
figure
subplot(3,1,1)
ezplot(imag(X),[-9 9]);
title('original signal');
%inverse Fourier transform
X1 =ifourier(X,t);
subplot(3,1,2)
ezplot(X1,[-5 5]);
title('inverse transform');
%Fourier Transform
X2 =fourier(X1,w)
subplot(3,1,3)
fplot(imag(X2),[-5 5]);
title('fourier transform');
.
