fault in matlab help?
Ältere Kommentare anzeigen
Hello,
I am working on my thesis and I have to use a matlab filter for this. When I using the example on this page butter I tried the exact same filter. But mine was all but stable. How is this possible? Can somebody try this aswell? Thank you!
[z,p,k] = butter(9,300/500,'high');
sos = zp2sos(z,p,k);
fvtool(sos,'Analysis','freq')

What version are you using? It works fine for me in R2013b.

Here's the result I get. Definitely does not match the documented example.
