+//Return the filter coefficients of a Hanning window of length M
+//Calling Sequence
+//hanning (M)
+//hanning (M, "periodic")
+//hanning (M, "symmetric")
+//Parameters 
+//M: real scalar, which will be the length of hanning window
+//Description
+//Return the filter coefficients of a Hanning window of length M.
+//If the optional argument "periodic" is given, the periodic form of the window is returned.  This is equivalent to the window of length M+1 with the last coefficient removed.  The optional argument "symmetric" is equivalent to not specifying a second argument.
