在 MATLAB Online 中打开

If you simply want the frequency transfer function, and not to identify the system (that requires the System Identification Toolbox):

H = fft(output)./fft(input);

where H is the complex frequency transfer function.

Did my answer solve your problem? Did it do what you needed?
