function [y, z, opt] = buffer (x, n, p, opt)
//This function buffers the given data into a matrix of signal frames
//Calling Sequence
//[y] = buffer (x, n)
//[y] = buffer (x, n, p)
//[y] = buffer (x, n, p)
//[y, z, opt] = buffer (...)
//Parameters
//x: Data to be buffered
//n: Positive integer equal to number of rows in the produced data buffer
//p: Integer less than n, default value 0
//opt: In case of overlap, it can be a vector of length p or the string "nodelay", In case of underlap, it is an integer between 0 and p
//Description
//This function buffers the given data into a matrix of signal frames
//Examples
//buffer(1,3,2)
//ans =
// 0 0
// 0 1
// 1 0
//This function is being called from Octave
