Fourier Series Tools Matlab script

Publisher review:
Fourier Series Tools - Create and manipulate Fourier Series using Function Handles FSfun = FSCREATE(...) creates a function handle FSfun containing the complex exponential Fourier Series described by its input arguments.The created Fourier Series function has the following features:SYNTAX DESCRIPTIONFSfun(t) evaluate function at the points in numerical array t.FSfun('tag') return the Tag string stored in FSfun.FSfun('coef') return Fourier Series coefficient row vector, Kn.FSfun('period') return function period, T.FSfun('size') return number of harmonics, N.FSfun('avg') return DC or average value.FSfun('msv') return mean square value (Parseval's Theorem).FSfun('max') return maximum function value.FSfun('min') return minimum function value.FSfun('thd') return total harmonic distortion relative to fundamental.FSfun('one') return one-sided line spectra amplitude vector, i.e.,[ |K(0)| 2*|K(1)| ... 2*|K(N)| ]FSfun('phase') return one-sided line spectra phase vector in Degrees, i.e.,[ angle(K(0)) angle(K(1)) ... angle(K(N)) ]FSfun('sine') return a vector of the one-sided Fourier Series sine coefficients, sine portion of trigonometric FS formFSfun('cosine') return a vector of the one-sided Fourier Series cosine coefficients, cosine portion of trigonometric FS formFSfun('all') return a structure having field names equal to the above string arguments with contents equal to associated data as described above, e.g., out.coef is the coefficients.FSfun('plot') create a TIME plot of one period of the Fourier SeriesFSfun('spectra') create a STEM plot of the one-sided spectraFSfun( {'area', [Tmin Tmax]} ) returns the area under the Fourier Seriesover the time range Tmin
