Introduction

In this tutorial we learn how to install libmatheval on Fedora 34.

What is `libmatheval`

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. libmatheval 1.1.11 15.fc34 x86_64 42 k libmatheval-1.1.11-15.fc34.src.rpm fedora Library for parsing and evaluating symbolic expressions input as text http GPLv3+ GNU libmatheval is a library (callable from C and Fortran) to parse and evaluate symbolic expressions input as text.
