Matrix & Linear Algebra Calculator
Calculate determinants, inverses, transposes, RREF, matrix arithmetic and solve Ax = b.
Matrix A
Matrix B
Vector b
Type directly into the matrix cells, then choose an operation.
Matrix operations
Type values directly into the matrix grid. Use Tab or arrow keys to move between cells. Determinant and inverse require a square matrix; multiplication requires compatible dimensions.
The RREF and linear-system functions use numerical row reduction, so very ill-conditioned matrices can accumulate floating-point error.
