**Note**: One interface for all**matrices**including**augmented matrices**representing**simultaneous systems of linear equations**.

This online **matrix calculator** remembers the **dimensions** and entries of all matrices that you enter and whether a matrix is **augmented** for **solving systems of linear equations**.

The matrix calculator allows you to perform **matrix addition**, **multiplication**, find **matrix inverses**, etc.) with *real* or **complex matrices** and **solve systems of linear equations** with real or complex coefficients.

To fill or edit a **matrix** select a named matrix from the drop-down list and set its dimensions and fill the matrix with numbers (real numbers, imaginary numbers or, in general, complex numbers)or numerical expressions of them.

You can change 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.
