  - rotateLocal
```
public Matrix2f rotateLocal(float angle)
```
    Pre-multiply a rotation to this matrix by rotating the given amount of radians about the origin.
    The produced rotation will rotate a vector counter-clockwise around the origin.
    If M is this matrix and R the rotation matrix, then the new matrix will be R * M. So when transforming a vector v with the new matrix by using R * M * v, the rotation will be applied last!
    In order to set the matrix to a rotation matrix without pre-multiplying the rotation transformation, use rotation().

    Parameters:
    
    angle - the angle in radians to rotate about the X axis
    
    Returns:
    
    this
