upsamplefill This function upsamples a vector interleaving given values or copies of the vector elements. y = upsamplefill (x, w) y = upsamplefill (x, w, cpy) 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 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.
