RotationMatrix

inline Matrix22 RotationMatrix(float theta)

Creates a 2D rotation matrix for the given angle.

Constructs a rotation matrix that rotates points counter-clockwise by the specified angle in radians. The matrix has the form: | cos(θ) -sin(θ) | | sin(θ) cos(θ) |

Parameters:

theta – [in] Rotation angle in radians

Returns:

2x2 rotation matrix
