Hi, I had a question about the `Matrixfilter/N=3 median` function.

Does this use the running median for the 3 points before and after the principle point?

I ask, because I have a 2D array that is a result of the concatenation of overlaid traces on a graph. I would like to use the running median in the Y and Z direction as they appear in the graph. I am unsure whether the Matrixfilter does this.
MatrixFilter applies its filtering algorithms to the NxN square around the pixel in question, so the answer is No, it's not suitable for your purpose.

Use Smooth/M=0 applied to the individual waves before concatenating them.
