示例1: Matrix3x2DeterminantTest1
public void Matrix3x2DeterminantTest1()
{
Matrix3x2 a = new Matrix3x2();
a.M11 = 5.0f; a.M12 = 2.0f;
a.M21 = 12.0f; a.M22 = 6.8f;
a.M31 = 6.5f; a.M32 = 1.0f;
Matrix3x2 i;
Assert.IsTrue(Matrix3x2.Invert(a, out i));
float detA = a.GetDeterminant();
float detI = i.GetDeterminant();
float t = 1.0f / detI;
// only accurate to 3 precision
Assert.IsTrue(System.Math.Abs(detA - t) < 1e-3, "Matrix3x2.GetDeterminant was not set correctly.");
// sanity check against 4x4 version
Assert.AreEqual(new Matrix4x4(a).GetDeterminant(), detA);
Assert.AreEqual(new Matrix4x4(i).GetDeterminant(), detI);

public void Matrix3x2InvertTest1()
