MedianFilter

The MedianFilter calculates the output for $$N$$ one-dimensional digital filters. Where the input, $$x$$, is a ($$N$$ x 1) vector of inputs and the output, $$y$$, is a ($$N$$ x 1) vector of outputs. The filter is described by number of observations, $$obs$$.

$$y[n] = median(x[n] + x[n-1] + ... + x[n-obs])$$
