WHAT IS IT?
GNU libmatheval is a library which contains several procedures that make it possible to create an in-memory tree from the string representation of a mathematical function over single or multiple variables. This tree can be used later to evaluate a function for specified variable values, to create a corresponding tree for the function derivative over a specified variable, or to write a textual tree representation to a specified string. The library exposes C and Fortran 77 interfaces.
REQUIREMENTS
GNU autotools are employed for this project, so library should be compilable on any UNIX variant. Still, compilation is verified on NetBSD 1.6 and Slackware GNU/Linux 9.1 only. Library (actually, test suite) requires Guile to be present.
INSTALLATION
For detailed GNU libmatheval installation instructions, see INSTALL
document. For impatient, simple sequence of:
./configure
make
make install
will do the job.
DOCUMENTATION
Documentation for GNU libmatheval is available as a Texinfo manual.
After installation, issue command:
