Matrix workspace
Add, multiply, invert and row-reduce matrices with exact fractions and explicit dimension checks.
Supply A and, for binary operations, B. Matrices contain 1 to 12 rows and columns. Add and subtract require equal shapes; multiply requires matching inner dimensions. Determinant and inverse require square matrices; a singular inverse is rejected. Scale requires a scalar. Transpose, row reduction and rank are also supported. All entries and row operations use reduced exact fractions. All processing stays on your device. Paste JSON with dot decimals; quote exact fractions and large integers. Input is limited to 100,000 characters and 100 digits per scalar. Exact results use reduced fractions, with a 1,024-digit and 200,000-step arithmetic bound. Enumeration is limited to 10,000 complete results and 1,000,000 search steps; exceeding a bound returns an error, not a partial answer. Geometry uses floating-point approximations. JSON and typed JSON Pointer CSV retain the complete input, results, constraints and worked steps. Reports are limited to 4,000,000 JSON and 8,000,000 CSV characters. Each calculation uses a disposable worker with a 10-second timeout. Search and sort the first 200 preview rows. Copy result copies the summary. Download JSON or CSV for every result and worked step. Geometry tools also provide a downloadable SVG diagram. Supply A and, for binary operations, B. Matrices contain 1 to 12 rows and columns.

How to use Matrix workspace
- Paste a JSON example and edit its documented fields. Keep machine field names unchanged.
- Choose a supported operation and review the stated domain and bounds.
- Review the result and download the complete JSON or CSV report, including worked steps.
