In symbolic tool box, there is a function called fourier which is supposed to give the FT of a function. Example below works
syms x y
f = exp(-x^2);
fourier(f, x, y)
But I find that this does not work. why?
syms x y
f = exp(-x^4);
fourier(f, x, y)
How do you represent a rectangular pulse function in MATLAB so that I can get the FT of it?
rect(t) = 1 if t is between -0.5 and 0.5 inclusive and zero outside.

Rectangular pulse that is 1 between A and B is
Heaviside(x-A) - Heaviside(x-B)
