For free packaged matrix solvers (for Windows PCs), which read and write Excel-compatible files, click here. 

 

For our C++ software library for dense systems of equations, click here.

The file matrix.h includes code for algorithms up to a robust least-squares solution for any shape system.

The file rejtrix.h extends matrix.h to have solvers which include regularization and constraints.
