## Package jv.vecmath Description

Vector and matrix classes for double and integers support simple linear algebra functionality. Vectors have variable dimension and are used, for example, as vertices of geometries.

Basic support for 2D, 3D, 4D and ND affine geometry.

Support for large matrices, sparse matrices and numerical linear algebra methods is available in the package `jvx.numeric`.
