Error using snr

Expected input number 2, Fs, to be a scalar.

Answer 1

This error means that the second input argument to the function snr is interpreted by MATLAB - based on how your code calls snr - to be the sampling rate Fs, and the sampling rate is expected to be a scalar, but your code has supplied a non-scalar second input argument.

If you share how your code calls snr, I can maybe be more specific on how you can avoid this error.
