hi. this is my code:

close all
clear all
syms t;
f=1*(t>=-1 & t<=1);
w=pi;
FT= int(f*exp(-i*w*t),-inf,inf);
ezplot (FT);
axis([-2,2,-2,2]);

this is result:

Do not try to use logical masking with symbolic expressions. t>=-1 evaluates (at best) to TRUE or FALSE, not to 0 or 1. Use piecewise() instead.

By the way, the integral is 0.
