Determinant, inverse, RREF, rank, eigenvalues, transpose, and matrix multiplication with step-free instant results
Run an operation…
Determinant and inverse use Gaussian elimination with partial pivoting; RREF reports the matrix rank; eigenvalues come from the QR algorithm and handle complex conjugate pairs. Paste matrices of any size straight from a spreadsheet (tabs, spaces, or commas all work). Ideal for checking linear algebra homework — determinants, solving systems, eigen-decompositions — without firing up MATLAB or NumPy.
