How to use Matrix Operations Calculator
Matrix products use compensated dot products. Square diagnostics use partial-pivot elimination with a precision threshold.
- Enter matrix a (json), matrix b (json, for add/product).
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
Good to know
- Rectangular JSON matrices up to 8×8, entries magnitude at most 1e12. Singular or poorly resolved inverses are rejected. This does not evaluate expressions.
- Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
