leopard is a linear, symmetric, positive definite or indefinite solver. The basis of the algorithm is a multifrontal factorization, that can handle indefinite cases with numerical pivoting.
The solver itself consists of a single header leopard.h describing the API and an accompanying .so file containing the code.
Any programming language able to call C-functions should be able to use the header and .so file to use the solver.
From the root folder of the project
mkdir build
cd build
cmake ..
make
./leopard-test
Generally speaking there are two things that need to be done:
- Include the
leopard.hheader to expose the leopard-API to your application. - Link your application with
libleopard.soso that the final binary can run leopard code.
A .zip with leopard.h and libleopard.so is available at: https://leopard-releases.mortenlysgaard.com/leopard-v0.1.0.zip
See CMakeLists.txt for an example of how to integrate the solver into your CMake project.
For other build systems, a similar approach to what is done in CMakeLists.txt can be used.
I would really like to see leopard being used in the wild, and thus I would be happy to assist and help in integrating into your specific build system.
