Hello, I want to use sgoalyfilt(x,order,framelen) but gets the error "Input arguments must be 'double'" and I cant´t understand why it dosn't work?

I use it like this:

order=4;

framelen=556497; % dosen't matter if I use 51 or 5 either, it gives the same error

P1_filt = sgolayfilt(P1,order,framelen) % where P1 is my measures values in a vector 1112992X1

Grateful for some help!

hello Anna

are you sure P1 is type double ?

the code works on my side with dummy rand input

 P1 = randn(1112992,1);
 order=4;
framelen=5111; 
 P1_filt = sgolayfilt(P1,order,framelen); % where P1 is my measures values in a vector 1112992X1

oh, miss that point! Now I used double(P1) and it works. Tanks for the help!
