**Online Matrix Calculator** to perform **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*. Find the **rank** of a matrix, and transform matrices to **lower triangular**, **upper triangular** and **reduced row echelon form**s. Complete instruction

**Note**: One interface for all **matrices** including **augmented matrices** representing **systems of linear eqautions**! The **matrix calculator** remembers the **dimensions** and entries of all matrices and wether a matrix is **augmented** or not. Just select a named matrix from the drop-down list and set its dimensions and fill the matrix with real or complex numbers.
You can increase the dimensions of a *selected* **matrix** by adding **rows** or **columns** to it by pressing the **+** (*insert row* or *insert column*) buttons provided. You can also set the dimensions of a selected matrix by entering the number of its **rows** or **columns** in the text boxes provided or, convinently, by pressing the numbered buttons on the left of a row or above a column, respectively.
