Package com.powsybl.math.matrix

This package contains utility classes around matrix modelling and LU decomposition. It is based on well known underlying libraries.

• Jama for dense matrix: only intended to be used for small matrices and unit testing.
• SuiteSparse KLU for sparse matrix: can be used with large sparse data
