//Parameters 
//m: positive integer value
//y: output variable, vector of real numbers
//Description
//This is an Octave function.
//This function returns the filter coefficients of a modified Bartlett Hann window of length m supplied as input, to the output vector y.
//Examples
//barthannwin(4)
//ans  =
//    0.    
//    0.73  
//    0.73  
//    0.
