This function buffers the given data into a matrix of signal frames
[y] = buffer (x, n) [y] = buffer (x, n, p) [y] = buffer (x, n, p) [y, z, opt] = buffer (...)
Data to be buffered
Positive integer equal to number of rows in the produced data buffer
Integer less than n, default value 0
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
