BasicMatrix

The BasicMatrix concept provides a minimalist interface for accessing elements from a 2 dimensional table of values.

Refinement of

none

Notation

| {M,I,V} | The matrix, index, and values types that together model the BasicMatrix concept. | | A | An object of type M. | | i, j | Objects of type I. |

Associated Types

none

Valid Expressions

| A[i][j] | Returns a reference to the element object stored at index (i,j)
Return type: V& for mutable A or const V& for constant A. |

Complexity guarantees

Element access is constant time.

Concept Checking Class

template <class M, class I, class V>
  struct BasicMatrixConcept
  {
    void constraints() {
      V& elt = A[i][j];
      const_constraints(A);
      ignore_unused_variable_warning(elt);
    }
    void const_constraints(const M& A) {
      const V& elt = A[i][j];
      ignore_unused_variable_warning(elt);
    }
    M A;
    I i, j;
  };
