The matrix calculator supports all basic linear algebra operations. Work with matrices up to 10x10.
Transposition — swapping rows and columns
Determinant — calculation for square matrices
Inverse matrix — if the determinant is non-zero
Matrix rank — using Gaussian elimination
Specify the matrix dimensions (rows x columns)
Fill in the cells with numerical values
Use a period as the decimal separator for fractional numbers
Select the desired operation from the list
To multiply matrix A(m×n) by matrix B(p×q), n must equal p. The result will be a matrix of size m×q.
The determinant is calculated only for square matrices. For 2×2 matrices, the formula ad - bc is used. For larger matrices, expansion along a row or column is applied.
Results are displayed with step-by-step intermediate calculations, which helps verify correctness and understand the algorithm.
