Hi,

I have data in a 2D matrix format and it has a periodic noise component and I would like to smooth it. It is easy to do what I want in a 1D function with analysis --> signal processing and smooth, is there a convenient way to expand this to a matrix of data? I guess the easiest way would be to have the algorithm performed with all the rows ...

thanks for helping me,
Martin

Hi Martin,

How about "analysis --> signal processing --> 2D FFT Filters" to run the Low Pass filter?

Or, you can try to convert the matrix "Data" to an image (under Image menu), then you can apply various spacial filters.
