Can i do Wavelet coherence in MATLAB R2014a ?

I'm using MATLAB R2014a and couldn't able to use the function ' wcoherence'. When I run the program it shows:

Undefined function 'wcoherence' for input arguments of type 'double'.

When I used the old function 'wcoher' it works. What should I do to use 'wcoherence' in R2014a?

To use that function in R2014a what you should do is become a Mathworks employee or intern and get authorization to back-port the function to the r2014a version and issue the new version as a Service Package to r2014a. Then you would go back to your r2014a version and install the service package and then go ahead with using the function.

Note that you will need to be very very convincing as to why Mathworks should invest the necessary resources. I cannot even convince them to make the documentation for r2014a available -- the appropriate internal people tried to convince Mathworks but management did a cost benefit analysis and says that keeping the documentation available is not worth the expense. So realistically speaking I do not believe that Mathworks would agree to you making those changes to their code base.

Might I suggest that it would be a great deal easier for you to upgrade to R2016a or later rather than getting aapproval for this project once you have become a Mathworks staff member or intern?
