Detailed Description

template<typename T>
struct blaze::IsSubmatrix< T >

Compile time check for submatrices.

This type trait tests whether or not the given template parameter is a submatrix (i.e. a view on the part of a dense or sparse matrix). In case the type is a submatrix, the value member constant is set to true, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to false, Type is FalseType, and the class derives from FalseType.

using MatrixType2 = blaze::DynamicMatrix<double>;
using MatrixType3 = blaze::CompressedMatrix<float>;

MatrixType2 B( 100UL, 200UL );
MatrixType3 C( 200UL, 250UL );
using SubmatrixType1 = decltype( blaze::submatrix<2UL,2UL,4UL,8UL>( A ) );
using SubmatrixType2 = decltype( blaze::submatrix<aligned>( B, 8UL, 8UL, 24UL, 32UL ) );
using SubmatrixType3 = decltype( blaze::submatrix( C, 5UL, 7UL, 13UL, 17UL ) );
