### Command

- INVERT_MATRIX <matrix array>

Set an array variable to the transformation matrix required to invert the current transformation stored in that array.

### Parameters

- <matrix array>
- A transformation matrix contains 12 values. These are stored in an array variable that must be defined to hold at least 12 values. If the array variable is defined with a size of more than 12, the first 12 values are used for the transformation matrix.

### Example

- GLOBAL MAT1(12)
- GET_SCALE_MATRIX MAT1, 0.5
- INVERT_MATRIX MAT1
