ES libraries

🚧 Under construction.

Synopsis

This is a collection of libraries that is being developed mostly for educational purposes.

esu: utilities library

esl: linear algebra library

• Dense matrices and vectors of strandard and user-defined types with static and dynamic extents
• Matrices with static extents can be used in constexpr context
• Sub-matrix (block) and transposed views
• Expression templates
• Sparse matrices with CSR storage scheme
• Some operations like X = Y or X += Y with float, double, std::complex<float>, and std::complex<double> matrix elements are mapped into MKL routines
• Export in MATLAB .mat and Gnuplot binary matrix files
• MKL inspector-executor sparse matrix wrapper
• MKL Pardiso linear solver and MKL Feast eigensolver wrappers
• GDB pretty printing

esf: finite elements library

• 1D meshes
• 2D meshed based on half-edge datastructure
• Vertex, edge and face iterators and views
• 1D and 2D Lagrange elements of variable degree that is fixed at compile-time
• 2D⊗1D Lagrange elements
• Guass and Dunavant rules for itegration
• Matrix-based linear, non-linear and eigensolvers
• Mesh faces colouring and multi-threaded matrix assembly
• Import from Gmsh mesh files, export into VTK, Matlab and Gnuplot files
• GDB pretty printing

Dependencies

• Intel MKL

Requires C++17/C++20 compiler (the only C++20 feature used is template parameter list for generic lambdas P0428R2). Tested with GCC 8.3.0.
