Fourier Series Transform and Piecewise Plotter

this program will plot any piecewise functions for fourier series transform only... with 't' as the variable.. and limits will be any number you like. this was one of our final projects in Signal Processing... i hope this program will also be able to help you grow in your understanding in Matlab... though i think there are a lot of loop holes in this... but its one thing that i have not seen in the internet... so feel free to use it...
