When I use this code, I get the following error:Error using plot Data cannot have more than 2 dimensions. Maybe it's because I extract data from a 3D matrix?
[B,A] = butter(4,0.6); %standaard een low-pass filter. 4 = order. 0.6 = cutoff.
Gefilterde_data = filtfilt(B, A, data_stair_rise(welke_pp,i_testen).VideoSignals);
plot(Gefilterde_data);

There is a plot3() function you can use instead. Try that.

Already tried that. But than he gives an error 'not enough input arguments'...

Then read the help and supply all the input arguments it wants.
