z |
numeric or complex scalar or vector. |
The usual trigonometric cotangens, cosecans, and secans functions and their inverses, computed through the other well known – in R – 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.
