I am a beginner of Matlab and I was trying to resample y by this resample function
but i got an error: " Incorrect number or types of inputs or outputs for function resample. "
please tell me what is the problem if you know. thanks a lot.
load handel.mat
y = y(:);
Fs = 8192;
fc = 2e5;
Fs_new = ceil( (Fs/2 + fc) / Fs * 2 ) * Fs;
y_resampled = resample(y,Fs_new,Fs);

Set a breakpoint at that line and step into resample to further investigate.

Ran in:
An alternative approach could be to creeate a timetable and then use the retime function —
load handel.mat
y = y(:)
y = 73113×1
0 -0.0062 -0.0750 -0.0312 0.0062 0.0381 0.0189 -0.0250 -0.0312 -0.0750

Fs = 8192;
fc = 2e5;
t = linspace(0, numel(y)-1, numel(y)).'/Fs; % Create Time Vector
Fs_new = ceil( (Fs/2 + fc) / Fs * 2 ) * Fs
Fs_new = 409600
% y_resampled = resample(y,Fs_new,Fs);
ytt = timetable(seconds(t), y) % Original ‘timetable’
ytt = 73113x1 timetable

These are part of core MATLAB, so you should have them.
