1D med filter

MATLAB movmedian Function for K-Point Median Values

M = movmedian(A, k) calculates a local k-point median array, where each median is computed over a sliding window of length k across neighboring elements of A. For an odd k, the window centers on the current element. For an even k, the window centers on the current and previous elements. The window size adjusts automatically at the endpoints when there aren't enough elements to fill the window, calculating the median only over the elements that fit. The result M maintains the same size as A.M

Movmedian() is built into base MATLAB, unlike medfilt1() which is in the Signal Processing Toolbox.
