Hi. Are there any resources or tutorials or references out there that would be helpful to  a newbie to SciLab filtering functions? I just want to filter some data – at this point, I don't even care what kind of filter – just want to learn how!

At first, I thought I'd try an IIR, but I couldn't figure out how to generate the coefficients.

//y = filter(num,den,x)

Then, I stumbled onto ffilt, which seems to generate FIR coefs, but where's the actual FIR filter function? Is it "convol"? I tried this:

plot(fft(convol(ffilt("hp",40,100),r)))

It does something, but I'm not sure what. Am I getting close?

Hi

I am not used ot filters, but I know there is a how to here: http://help.scilab.org/docs/5.4.1/en_US/DesignEllipticFilter.html  (this is available in french also)
from there, i suggest you navigate throught the "see also sections"

you can also have a look here: http://help.scilab.org/docs/5.4.1/en_US/section_dbbac6be408104de3049eddefaf6b9c9.html

the content of this webpage is also available in your computer, type "help" in the console and navigate.

I hope the "how to" (1st link) will help you
