Méthode Description
GetAngle ( ) : float

Extract the angle from this matrix (assumed to be a rotation matrix).
GetInverse ( ) : Mat22

Compute the inverse of this matrix, such that inv(A) * A = identity.
Mat22 ( System.Vector2 c1, System.Vector2 c2 ) : System

Construct this matrix using columns.
Mat22 ( float angle ) : System

Construct this matrix using an angle. This matrix becomes an orthonormal rotation matrix.
Mat22 ( float a11, float a12, float a21, float a22 ) : System

Construct this matrix using scalars.
Multiply ( System.Vector2 vector ) : System.Vector2
Set ( System.Vector2 c1, System.Vector2 c2 ) : void

Initialize this matrix using columns.
Set ( float angle ) : void

Initialize this matrix using an angle. This matrix becomes an orthonormal rotation matrix.
Solve ( System.Vector2 b ) : System.Vector2

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.
operator ( ) : Mat22
