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

Use Online Graphing Calculator to solve any one-variable equation in x

**Note**: You can set the number of **rows** or **columns** of a selected **matrix** by pressing the numbers appearing on the left or above the selected **matrix**, respectively. You can also **add rows** or **add columns** by pressing the relevant **+** button. The matrix calculator remembers your settings for all matrices.
