Hi, I'm currently trying to design a bandpass filter to filter a series of input data y between 1-30 Hz. Acording to the syntax for bandpass, y is my x value, and (1,30) is my wpass value, but trying to run the command results in an 'invalid use of parentheses' error. Can someone explain why this is the case?
d = bandpass(y, (1,30));

请先登录，再回答此问题。

You need to use brackets, not parentheses:
y = rand(200,1);
Fs = 100; % Sampling rate, e.g., 100 Hz
d = bandpass(y, [1,30], Fs);
