Demo of how to find Fourier Series of periodic pulses

Demonstration of how Fourier Series application in MATLAB to find curve fitting of periodic pulses

Fourier_Series_Approx_PULSE.m creates a periodic rectangular pulses and
computes Fourier Series according to which curve fitting with user chosen number of terms, viz. coefficients of Fourier Series is performed and curve fitting results will be plotted for every selected number of Fourier series. All user selection entries will be in the pop
up GUI windows and further evaluations are performed according the user.
