What you can do
- Follow exact matrix row operations from input to result.
- Explore eigenvalues, eigenvectors, and verification residuals.
- Study numerical differential-equation solutions iteration by iteration.
Features & availability
All twelve Math Workbench calculator families are free on this website, including matrix operations, linear systems, eigenvalues, differential equations, root finding, integration, and interpolation. Each has worked steps, examples, and explicit numerical limits. The standalone application remains pre-release.
