Returns whether the given zero vector is in default state.
- Parameters
-
v | The zero vector to be tested for its default state. |
- Returns
- true in case the given vector's size is zero, false otherwise.
This function checks whether the zero vector is in default (constructed) state, i.e. if it's size is 0. In case it is in default state, the function returns true, else it will return false. The following example demonstrates the use of the isDefault() function:
bool isDefault(const DiagonalMatrix< MT, SO, DF > &m)
Returns whether the given diagonal matrix is in default state.

Optionally, it is possible to switch between strict semantics (blaze::strict) and relaxed semantics (blaze::relaxed):
if( isDefault<relaxed>( z ) ) { ... }

constexprnoexcept |
Returns whether the invariants of the given zero vector are intact.
- Parameters
-
v | The zero vector to be tested. |
- Returns
- true in case the given vector's invariants are intact, false otherwise.
This function checks whether the invariants of the zero vector are intact, i.e. if its state is valid. In case the invariants are intact, the function returns true, else it will return false. The following example demonstrates the use of the isIntact() function:
bool isIntact(const DiagonalMatrix< MT, SO, DF > &m)
Returns whether the invariants of the given diagonal matrix are intact.
