We now want to apply this same rotation but about an arbitrary point P: As we can see its orientation is the same as if it had been rotated about the origin, but it has been translated to a different point on space by the rotation. In order to prove this and to calculate the amoun...
In the solving process, LU factorization with partial rotation and row interchange is performed on to factor the LU into a form of , where is a transpose matrix, is a unit lower triangular matrix, and is an upper triangular matrix. The system of linear equations is solved by the result ...
