This function upsamples a vector interleaving given values or copies of the vector elements.
y = upsamplefill (x, w) y = upsamplefill (x, w, cpy)
scalar, vector or matrix of real or complex numbers
scalar or vector of real or complex values
can take in "true" or "false", default is false
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.
