SAL Home MATH Computer Algebra System


This package is designed to do simple symbolic derivatives. At the heart of the library is a routine (take_deriv) which takes an expression and a variable (both passed as strings) and returns either another string (which should be the derivative of the expression passed in) or NULL in which case there is a syntax error in the original expression.

Layered on top of this routine is a hook into Tcl which allows you to make use of this subroutine directly from Tcl.
