%SELMETH_PTE selects and runs the desired TEQ design method
% for Per Tone Equalizer Design.
% [WM, D, title_str, py, pX] = 
%           SELMETH_PTE(method,inputSignal,receivedSignal,noise,channel,
%  Nw, N , barflag))
% returns the per tone equalizer banks in WM. D the optimal delay, MSE
% the mean squared error, Title_str is a string with the name of the called 
% method in it. py, pX are matrices of processed input and output data 
%
% method is a integer defining which method to be used, inputSignal is the 
% transmitted signal, receivedSignal is the received signal, noise is the 
% received noise, channel is the channel impulse response, Nw the number
% of taps in the TEQ, Barflag is a flag if set to one enables the 
% progress bar during calculations, N is the FFT size in the DMT modulation
