Subtract this matrix and a specified matrix.
static CL_Mat4<Type>_Mat4< e >::subsubsubtract( const CL_Mat4 < Type > & matrix_1, const CL_Mat4 < Type > & matrix_2); CL_Mat4<Type>&a_Mat4< e >::s::subtractactact( const CL_Mat4 < Type > & sub_matrix);
Detailed description:
This subtracts the matrix as follows: this = mult - this
