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