- Use the buttons on the top of the
**Matrix Calculator**to calculate the**determinant**,**inverse**,**adjugate**,**reduced row echelon form**,**upper**and**lower triangular**, or**transpose**of the**matrix A**(*selected initially*), which you can change its*entries*and its*dimension*by clicking the buttons to the left of the rows and the buttons above the columns.You can also work with other matrices as above by first selecting them.

- Additionally, you can do
**matrix**calculations under the**More Quick Calculations**menu for the more frequently used**matrix**operations involving more than one**matrix**. - To use the real power of this online
**Matrix Calculator**enter any**matrix**expression in the expression box provided and press**Calculate**. Your**matrix expression**can contain any of the matrices listed.You can enter any

**matrix**expression such as**det(A+inv(AB+3C))*(3C-D)**(the use of * is optional).*This*.**Online Matrix Calculator**is the only**matrix calculator**which can perform arbitrarily complicated**matrix expressions** - To solve a
**system of linear equations**(or work with**augmented matrices**) first select**Linear System**and enter the**coefficient matrix**with the column vector to form the**augmented matrix**and press**Solve**. - You can use
**any numeric expressions**, e.g.,**1/2 + 2sin(π/3)**for**matrix**entries.The matrix entries can also contain

**Complex Numbers**.
