I am trying to find the fourier transform of sinc (t) function, which acc. to the mathematics, should be a rectangular function ranges between (-.5, 0.5), but what I am getting is totally different than that. May I request you to help me with this.
Is their any way to calculate normal fourier without using fft function?
The MATLAB code is attached with this message.

Well, before plotting try to check what your variable fy is:
whos fy
Then when you see that it is a complex variable you have to check how matlab plots complex variables, once you've done that try:
fy = fftshift(fy);
plot([abs(fy);angle(fy);real(fy);imag(fy)]')
