Matrix inverter tool What is a matrix inverter?
This tool inverts matrices. One matrix is an inverse of another matrix if their product is the identity matrix. Matrices whose determinant is zero don't have an inverse. With this tool you can find an inverse matrix of any size, with the accuracy you want. You can set the separator between matrix elements and between rows for input and output matrices, and you can select Prettify Matrix option for nice formatting. Mathabulous!

Inverted Matrix With Auto Precision
In this example, the tool itself determines how many values to leave after decimal point, It does so because we turned out auto-accuracy option.

Matrix with Determinant Zero has no Inverse
In this example we use a matrix that has determinant value of 0 (two of its rows are equal). This matrix is singular and doesn't have an inverse matrix.
