Smoothing

expsmooth(v, a) Returns a smoothed version of the data in vector v generated by exponential smoothing with weight a.

medfilt1d(M, n) Returns the multichannel signal M, filtered with a median filter of length n.

movavg(v, n) Returns a smoothed version of the data in vector v created by taking a moving average with a window of width n.

Arguments:

• v is a complex-valued data vector or matrix.
• M is a real-valued vector or matrix. If M is a matrix, filtering is applied column by column.
• n is an integer, the moving average window width or median filter length.
• a is the exponential window parameter, 0 ≤ a ≤ 1.
