MATLAB: Problem to transform a signal with fft

Question

i have the signal

h(t)=sinc((10^3)*t)

and i want to transform it to fourier with fft. Can you tell me the right way because it confuses me?

Answer 1

http://www.mathworks.com/help/signal/ref/sinc.html

start_time = 0;
end_time = 20;   %for example
t = linspace(start_time, end_time, 501);   %create time vector
h = sinc(10^3*t);
hf = fft(h);

Now hf is the transformed value. It will have complex coefficients.
