Subtract this matrix and a specified matrix.
static CL_Mat2<Type>_Mat2< e >::subsubsubtract( const CL_Mat2 < Type > & matrix_1, const CL_Mat2 < Type > & matrix_2); CL_Mat2<Type>&a_Mat2< e >::s::subtractactact( const CL_Mat2 < Type > & subtract_matrix);
Detailed description:
This subtracts the matrix as follows: this = subtract_matrix - this
