have you checked your input arguments (x,y,days(1)) : size, type ?

Input Arguments

x — Input signal

vector of real values

Input signal, specified as a vector of real values. x must be a 1-D, real-valued signal. The two input signals, x and y, must be the same length and must have at least four samples.

y — Input signal

vector of real values

Input signal, specified as vector of real values. y must be a 1-D, real-valued signal. The two input signals, x and y, must be the same length and must have at least four samples.

ts — Sampling interval

duration with positive scalar input

Sampling interval, also known as the sampling period, specified as a duration with positive scalar input. Valid durations are years, days, hours, seconds, and minutes. You can also use the duration function to specify ts. You cannot use calendar durations (caldays, calweeks, calmonths, calquarters, or calyears).

You cannot specify both a sampling frequency fs and a sampling period ts.

fs — Sampling frequency

positive scalar | []

Sampling frequency, specified as a positive scalar.

If you specify fs as empty, wcoherence uses normalized frequency in cycles/sample. The Nyquist frequency is ½.

You cannot specify both a sampling frequency fs and a sampling period ts.
