Question

documentation of implementation of funtions

Dear Mathcad users,

 

I would like to have a more detailed description of the math behind the functions. For example today I was looking into the cross correlation functions crosscorr(S, K, [BC], [OV]). I would like to see the expressions that are used to calculate the results. Is there any place I can find this?

 

regards,

Joop

The algorithms are, to my knowledge, nowhere disclosed. As far as I know, many algorithms stem from the Numerical Recipes or are at least based upon them.

No sure, of course, if this also affects "crosscorr" which, as far as I am aware, was introduced just with Prime.

thanks for the reply. In the end I do not need the numerical algorithm but to use a function like crosscorr I must know what Math it does. What equations are solved?

Documentation sure was much better in older Mathcad versions, especially up to and including MC11.

Beginning with Prime the only "documentation" is the help system and as crosscorr is a newly introduced function all we have is the help
