Detailed Description
template<class _Field>
class LinBox::ScalarMatrix< _Field >
Blackbox for aI. Use particularly for representing 0 and I.
This is a class of blackbox square scalar matrices. Each scalar matrix occupies O(scalar-size) memory. The matrix itself is not stored in memory, just the scalar and the dimensions.
