buffer 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 (...) 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 This function buffers the given data into a matrix of signal frames
