Hi,
Here are several nice tutorial examples of matlab on Fourier Transform.

My impression is that this is homework. We give hints for homework, not complete code. (You must write the code. We will help you to get your code to run if you have problems with it.)
It is straightforward to compute the Fourier transform symbolically. You need to remember also to allow for the part of the signal that is zero in the time range that you are computing it.
You already discovered Hi how do i plot a halfwave rectifier signal in matlab? i tried the coding below and only got the fullwave (since you posted a Comment to it to request thatI look at this Question), all you then need to do is to read the documentation for fft and use that with the signal I provided in that Answer.

To get the amplitude (amplitude = magnitude) spectrum such as in the plot image, use the fftshift function, then plot using a symmetric frequency vector, for example:
sy = fftshift(y);
sf = linspace(-10,10, numel(sy));
then:
figure
stem(sf, sy)
or something similar.
