numeric or complex scalar or vector. |
The usual hyperbolic cotangens, cosecans, and secans functions and their inverses, computed through the other well known – in R – hyperbolic sine, cosine, and tangens functions.
Result vector of numeric or complex values.
These function names are available in Matlab, that is the reason they have been added to the ‘pracma’ package.
