Syntax

Description

mfunlist lists the special mathematical functions for use with the mfun function. The following tables describe these special functions.

You can access more detailed descriptions by typing

Limitations

In general, the accuracy of a function will be lower near its roots and when its arguments are relatively large.

Runtime depends on the specific function and its parameters. In general, calculations are slower than standard MATLAB calculations.
