SIMatrix4.TransposeInverseInPlace

説明

この行列を、それ自身の転置逆行列に設定します(特異行列でない場合)(this = Transpose(this^-1))。

スクリプト 構文

oBoolean = SIMatrix4.TransposeInverseInPlace();

戻り値

Boolean。行列 m が逆行列を持つ(特異でない)場合は True、逆行列を持たない場合は false。

1. VBScript の例

'
' This example demonstrates how to transpose and invert 
' a 4x4 matrix, store the result of the operation in 
' the first matrix, and then trap whether the invert
' and transpose operation was successful.
