Package org.tribuo.math.la Description

Provides a linear algebra system used for numerical operations in Tribuo.

There are Dense and Sparse vectors and Matrices, along with a DenseSparseMatrix which is a dense array of sparse row vectors.

It's a single threaded implementation in pure Java. We're looking at ways of improving the speed using new technologies coming in future releases of Java.
