TomSym - Supported Functions

From TomWiki
Jump to navigationJump to search

Below is a list of functions that are overloaded for tomSym. That is: these functions accept symbolic input and then return symbolic expressions whose derivatives can be computed symbolically.

Most of these are standard Matlab functions, but some are special functions that are mostly used internally by tomSym for efficiency reasons.

In addition to the functions on this list, there are many functions that are supported because they consist entirely of other functions that are supported. For example, it is possible that functions which you have written yourself already work with tomSym. The easiest way to find out if a function is supported is to try to use it. If you don't get an error message, then it works!

We constantly add new functions to TOMSYM. If there's a function that you think would be useful, let us know and we might include it in a future TOMLAB release.
