A (sparse) matrix solver for python.
Solving Ax = b should be as easy as:
Ainv = Solver(A) x = Ainv * b
In pymatsolver I provide a number of wrappers to existing numerical packages. Nothing fancy here.
All solvers work with
scipy.sparse matricies, and a single or multiple right hand sides using
- L/U Triangular Solves
- Wrapping of SciPy matrix solvers (direct and indirect)
- Pardiso solvers now that MKL comes with conda!
- Mumps solver with nice error messages
I have not been able to get the pip install to work because of multiple dependencies on fortran libraries. However, the linux and mac installs are relatively easy. Note that you must have mumps pre-installed, currently I have only got this working for the sequential version, so when you are installing, you will need to point to that one. You can also look at the .travis.yml file for how to get it working on TravisCI.
From a clean install on Ubuntu:
apt-get update apt-get -y install gcc gfortran git libopenmpi-dev libmumps-seq-dev libblas-dev liblapack-dev # Install all the python you need! wget http://repo.continuum.io/miniconda/Miniconda-3.8.3-Linux-x86_64.sh -O miniconda.sh; chmod +x miniconda.sh ./miniconda.sh -b export PATH=/root/anaconda/bin:/root/miniconda/bin:$PATH conda update --yes conda conda install --yes numpy scipy matplotlib cython ipython nose git clone https://github.com/rowanc1/pymatsolver.git cd pymatsolver make mumps
This assumes that you have Brew and some python installed (numpy, scipy):
brew install mumps --with-scotch5 --without-mpi git clone https://github.com/rowanc1/pymatsolver.git cd pymatsolver make mumps_mac
If you have problems you may have to go into the Makefile and update the pointers to Lib and Include for the various libraries.
This command is helpful for finding dependencies. You should also take note of have happens when brew installs mumps.
