Free online Real/*Complex* **Matrix Calculator** and Real/*Complex* **System of Linear Equations Solver** to perform **matrix algebra**, calculate **matrix expressions** and solve **Linear System of Equation**. You can use this **Matrix Calculator** to solve **simultaneous system of linear equations** with complex coefficients or **complex augmented matrix**. You can use this **Matrix Calculator** to do simple operations such as **add**, **subtract**, **multiply** and even **divide** (*multiply by inverse of)* compatible **matrices**. Also use this **Matrix Calculator** to easily calculate the **determinant**, **inverse** and **adjugate** of *square matrices* and find the **rank** of a matrix. Also transform matrices to **lower triangular**, **upper triangular** and **reduced row echelon form**s. Full instruction

**Note**: One interface for all **matrices** including **augmented matrices** representing **systems of linear equations**! The **matrix calculator** remembers the **dimensions** and entries of all matrices and whether 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, conveniently, by pressing the numbered buttons on the left of a row or above a column, respectively.

This elegant **matrix calculator** deploys one single interface which can be used to enter multiple **matrices** including **augmented matrices** representing **systems of linear equations**!

In addition to **adding**, **multiplying** matrices, you can use this **matrix calculator** to calculate **determinant**, **inverse** and **adjugate** of *square matrices* and find the **rank** of any matrix. Also transform matrices to **lower triangular**, **upper triangular** and **reduced row echelon form**s.

You can also solve **systems of linear equation**s. The **linear equation solver** can solve any m × n linear equations.

Matrices can have **real**, **imaginary** and, in general, **complex numbers** as their elements. This **complex matrix calculator** can perform **matrix algebra**, all the previously mentioned **matrix operation**s and **solving linear system**s with **complex matrices** too.

Furthermore, this **matrix calculator** evaluates **matrix expressions** containing up to eight **real** or **complex matrices** and shows work.
