Linear Algebra Toolkit

Abstraction: Interactive web modules for practicing core linear algebra procedures

Key points:

• Created by P. Bogacki at Old Dominion University; first released May 2000, current version 1.25 (February 2019)
• Covers systems of linear equations: row operations, REF/RREF, solving systems, matrix inverse
• Determinant calculation via row operations
• Vector space modules: linear independence/dependence, span, basis finding, null space (with rank and nullity)
• Linear transformation modules: kernel (nullity, one-to-one check) and range (rank, onto check)
• Each module is a standalone interactive calculator designed for step-by-step practice
