gmx::PullCoordExpressionParser Class Reference

#include <gromacs/pulling/pullcoordexpressionparser.h>

Description

Class with a mathematical expression and parser.

The class handles parser instantiation from an mathematical expression, e.g. 'x1*x2', and evaluates the expression given the variables' numerical values.

Note that for performance reasons you should not create a new PullCoordExpressionParser for every evaluation. Instead, instantiate one PullCoordExpressionParser per expression, then update the variables before the next evaluation.
