This directory contains files related to linear algebra operations. Files such as NekMatrix, BlockMatrix and NekLinearSystem are fundamental to many of the operations we do within Nektar++. These files represent our attempt to encapsulate linear algebra operations in a way that make sense from the programmer perspective but for which we do not loose efficiency. As can be seen in these routines and throughout the code, we rely heavily on BLAS (Basic Linear Algebra Subroutines).
