**Online Matrix Calculator** to do matrix algebra, calculate matrix expressions including **complex matrices**. Solve **linear systems of equations** with real or complex coefficients. Add, subtract, multiply and divide (i.e., multiply by inverse of) compatible matrices. Calculate determinant, inverse and adjugate of square matrices. Use Gaussian elimination to reduce matrices to lower and upper triangular and reduced row echelon forms. Complete instruction

**Note**: You can add **rows** or **columns** by pressing the relevant **+** button. You can also set the number of **rows** or **columns** of a selected matrix by pressing the buttons appearing on the left or above the matrix, respectively.
