MATLAB: How to do the fourier transform

fourier transform

I need to compute the following equation using Fourier transform in Mat lab :

Integral with limit{infinity,-infinity] sin x/ x(x^2 + 1) dx

can someone help me. thanks in advance.

doc sin
doc fft
doc fftshift
doc abs
doc plot

Continuous and Discrete Fourier Transform are the same in the limit case of the steps being infinitesimals.

Other than that, they cannot be compared as they work on two different kinds of information.

doc fft
doc fftshift
doc abs
doc angle
doc plot
doc stem
doc xlabel
doc ylabel
doc grid
doc xlim
doc ylim
