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