File Information

[y_fl, Y_fl, f, Y, f_fl, fl_function, filter]=f4ts(y,Fs,filter,plot1)

filter that clean the signal from diffrent kind of noise. input : signal in time, Fs (frequency of sampelling), and the filter : a spacific frequency to filter, # of harmonics (can be default), shape of the filter : square(default), gaussian, lorentzian, and filter width@ Full width half max(can be default).
can be used in older ver. of matlab

please make a comment, so i could make it better. note that the filter work better on a signal with noise than on a clean signal.

changed the input from frequency domain to the raw time domain, and make is more simple to use, with a good example
