Hi,
Is there a function to apply a FIR filter to a data vector, like "response" in Mathcad?
I could write my own convolution, but it will become cumbersome at the beginning and end of the vector.

I found the remez function to generate arbitrary pass/stop band combinations, its nice. Are there also the more basic generators for high/low-pass filters somewhere?

You can map 2D, 3D to any math function.
Why not show something. Filter is too general
Filter/smooth ... Filter band ...

I don't think much of the Mathcad response 20 years old maybe.
In those days, they fight imitating analog filters.
Attach your signal data, what you want to do.

Hi. This function emulates the matlab filter function (https://uk.mathworks.com/help/matlab/ref/filter.html) Hope it's helps.
