# Matrix Determinant ## Description Returns the determinant of the matrix defined by input **In**. It can be viewed as the scaling factor of the transformation described by the matrix. ## Ports | Name | Direction | Type | Description | |:------------ |:-------------|:-----|:---| | In | Input | Dynamic Matrix | Input value | | Out | Output | Float | Output value | ## Generated Code Example The following example code represents one possible outcome of this node. ``` void Unity_MatrixDeterminant_float4x4(float4x4 In, out float Out) { Out = determinant(In); } ```
