Detailed Description

A symbolic expression. This class represent an arbitary symbolic expression. This can either be the special case of just a symbol or an arbitary expression consisting of a hierarchiy of operations consisting itself of expressions, symbols or constants.

Member Function Documentation

garbageCollect()

void fmatvec::SymbolicExpression::garbageCollect ( )

static

Garbage collect everything. The only "garbage" which can be left by this class are empty weak_ptr's stored in global maps. This routine removes such garbage.

parDer

FMATVEC_EXPORT SymbolicExpression parDer ( const SymbolicExpression &  dep, const IndependentVariable &  indep  )

friend

Generate a new SymbolicExpression being the partial derivate of dep with respect to indep (indep must be a symbol).
