why is 'wcoherence' not being recognised as a function?

trying to run a wavelet coherence analysis, but Matlab is not recognising the function 'wcoherence'. I am using version 2015b. Any ideas?

wcoherence was introduced in R2016a.

All MathWorks functions now have text at the bottom of the reference page that indicates the release in which they were introduced.
