bld-linalg

Basic linear algebra functions for Common Lisp

Why?

Because I only needed a few simple operations and didn't want the overhead of a full linear algebra library.

Treats 2D arrays as matrices
Overloaded arithmetic functions (using BLD-GEN) to implement addition, subtraction, and multiplication of matrices
Basic matrix processing like identity, diagonal, column & row vectors, sub-matrices, and matrix mapping
Frobenius norm
Jacobi method
LU decomposition
