この行列の逆行列(特異でない場合)を求めます(this = this^-1)。
Int32 SIMatrix4.InvertInPlace(); |
oBoolean = SIMatrix4.InvertInPlace(); |
Boolean。この行列が逆行列を持つ(特異でない)場合は True、逆行列を持たない場合は false。
/*
This example demonstrates how to set up a 4x4 matrix,
invert it and then trap whether the inversion was
successful
*/
// Create 4x4 matrices
var aValues = new Array(
2.0, 3.0, 0.0, 0.0,
1.0, 4.0, 0.0, 0.0,
0.0, 0.0, 1.0, 0.0,
0.0, 0.0, 0.0, 1.0
);
var m1 = XSIMath.CreateMatrix4(aValues);
var m2 = XSIMath.CreateMatrix4();
// Make the second matrix the inversion of the first
if ( m2.InvertInPlace() ) {
Application.LogMessage( "Success :-D" );
} else {
Application.LogMessage( "Failure :-(" );
}
// Expected result:
// INFO : Success :-D |
