Returns whether the given zero matrix is in default state.
- Parameters
-
m | The matrix to be tested for its default state. |
- Returns
- true in case the given matrix's rows and columns are zero, false otherwise.
This function checks whether the zero matrix is in default (constructed) state, i.e. if it's number of rows and columns 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:
Efficient implementation of an zero matrix.

bool isDefault(const DiagonalMatrix< MT, SO, DF > &m)
Returns whether the given diagonal matrix is in default state.
Definition: DiagonalMatrix.h:169
Optionally, it is possible to switch between strict semantics (blaze::strict) and relaxed semantics (blaze::relaxed):
if( isDefault<relaxed>( Z ) ) { ... }

Returns whether the invariants of the given zero matrix are intact.
- Parameters
-
m | The zero matrix to be tested. |
- Returns
- true in case the given matrix's invariants are intact, false otherwise.
This function checks whether the invariants of the zero matrix 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.
