//! This class implements the real matrix abstract data type. <br>
//!          Matrixes can have an arbitrary range which must be defined <br>
//!          at the declaration and cannot be changed after this declaration <br>
//!          math_Matrix(-3,5,2,4); //a vector with range [-3..5, 2..4] <br>
//!          Matrix values may be initialized and <br>
//!          retrieved using indexes which must lie within the range <br>
//!          of definition of the matrix. <br>
//!          Matrix objects follow "value semantics", that is, they <br>
//!          cannot be shared and are copied through assignment <br>
//!          Matrices are copied through assignement: <br>
//!          math_Matrix M2(1, 9, 1, 3); <br>
//!          ... <br>
//!          M2 = M1; <br>
//!          M1(1) = 2.0;//the matrix M2 will not be modified. <br>
//! <br>
//!          The exception RangeError is raised when trying to access <br>
//!          outside the range of a matrix : <br>
//!          M1(11, 1)=0.0// --> will raise RangeError. <br>
//! <br>
//!          The exception DimensionError is raised when the dimensions of <br>
//!          two matrices or vectors are not compatible. <br>
//!          math_Matrix M3(1, 2, 1, 2); <br>
//!          M3 = M1;   // will raise DimensionError <br>
//!          M1.Add(M3) // --> will raise DimensionError. <br>
//!          A Matrix can be constructed with a a pointer to "c array". <br>
//!          It allows to carry the bounds inside the matrix. <br>
//! Exemple : <br>
//! 	    Standard_Real tab1[10][20]; <br>
//! 	    Standard_Real tab2[200]; <br>
//! <br>
//!      math_Matrix A (tab1[0][0], 1, 10, 1, 20); <br>
//!      math_Matrix B (tab2[0],    1, 10, 1, 20); <br>
