Detailed Description

template<int Size = Dynamic, typename Precision = DefaultPrecision, typename Base = Internal::VBase>
class TooN::DiagonalMatrix< Size, Precision, Base >

A diagonal matrix.

Support is limited but diagonal matrices can be multiplied by vectors, matrices or diagonal matrices on either side.

Diagonal matrices can be created from vectors by using the as_diagonal() member function:

Vector<3> v = makeVector(1,2,3);
Vector<3> v2 = v.as_diagonal() * v;   // v2 = (1,4,9)

A vector can be obtained from the diagonal matrix by using the diagonal_slice() member function.
