function y = upsamplefill (x, w, cpy)
//This function upsamples a vector interleaving given values or copies of the vector elements.
//Calling Sequence
//y = upsamplefill (x, w)
//y = upsamplefill (x, w, cpy)
//Parameters
//x: scalar, vector or matrix of real or complex numbers
//w: scalar or vector of real or complex values
//cpy: can take in "true" or "false", default is false
//Description
//This is an Octave function.
//This function upsamples a vector interleaving given values or copies of the vector elements.
//The second argument has the values in the vector w that are placed in between the elements of x.
//The third argument, if true, means that w should be scalar and that each value in x repeated w times.
//Examples
//upsamplefill([0.4,0.5],7)
//ans =
// 0.4 7. 0.5 7.
