Determinant (LogiX node)
The Determinant node calculates the determinant of the input matrix.
When spawned from the node browser, this node accepts the float2x2 datatype by default. However, this node can be overloaded to accept 3x3 or 4x4 float matrices (as well as double type matrices) if appropriate wire is connected to an input.
The following image shows creating and taking the determinant of the identity matrix.
