49 GNU libmatheval is a library (callable from C and Fortran) to parse and evaluate symbolic
50 expressions input as text. It supports expressions in any number of variables of arbitrary
51 names, decimal and symbolic constants, basic unary and binary operators, and elementary
52 mathematical functions. In addition to parsing and evaluation, libmatheval can also compute
53 symbolic derivatives and output expressions to strings.
