Returns whether the given column is in default state.
- Parameters
-
column | The column to be tested for its default state. |
- Returns
- true in case the given column is component-wise zero, false otherwise.
This function checks whether the column is in default state. For instance, in case the column is instantiated for a built-in integral or floating point data type, the function returns true in case all column elements are 0 and false in case any column element is not 0. The following example demonstrates the use of the isDefault function:
Optionally, it is possible to switch between strict semantics (blaze::strict) and relaxed semantics (blaze::relaxed):
if( isDefault<relaxed>(
column( A, 0UL ) ) ) { ... }

|
inlinenoexcept |
Returns whether the invariants of the given column are intact.
- Parameters
-
column | The column to be tested. |
- Returns
- true in case the given column's invariants are intact, false otherwise.
This function checks whether the invariants of the column 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:
template<typename MT , bool SO, bool DF, bool SF>
bool blaze::isSame |
( |
const Column< MT, SO, DF, SF > & |
a, |
|
|
const Column< MT, SO, DF, SF > & |
b |
|
) |
| |
|
inlinenoexcept |
Returns whether the two given columns represent the same observable state.
- Parameters
-
a | The first column to be tested for its state. |
b | The second column to be tested for its state. |
- Returns
- true in case the two columns share a state, false otherwise.
This overload of the isSame function tests if the two given columns refer to exactly the same range of the same matrix. In case both columns represent the same observable state, the function returns true, otherwise it returns false.
