Detailed Description

Function Documentation

template<typename MT , bool SO>
void blaze::clear ( DenseRow< MT, SO > &  row)
inline

Clearing the given dense row.

Parameters
rowThe dense row to be cleared.
Returns
void
template<typename MT , bool SO>
bool blaze::isDefault ( const DenseRow< MT, SO > &  row)
inline

Returns whether the given dense row is in default state.

Parameters
rowThe dense row to be tested for its default state.
Returns
true in case the given dense row is component-wise zero, false otherwise.

This function checks whether the dense row is in default state. For instance, in case the row is instantiated for a built-in integral or floating point data type, the function returns true in case all row elements are 0 and false in case any row element is not 0. The following example demonstrates the use of the isDefault function:

// ... Resizing and initialization
if( isDefault( row( A, 0UL ) ) ) { ... }
template<typename MT , bool SO>
bool blaze::isnan ( const DenseRow< MT, SO > &  row)
inline

Checks the given dense row for not-a-number elements.

Parameters
rowThe dense row to be checked for not-a-number elements.
Returns
true if at least one element of the row is not-a-number, false otherwise.

This function checks the dense row for not-a-number (NaN) elements. If at least one element of the row is not-a-number, the function returns true, otherwise it returns false.

// ... Resizing and initialization
if( isnan( row( A, 0UL ) ) ) { ... }
template<typename MT , bool SO>
void blaze::reset ( DenseRow< MT, SO > &  row)
inline

Resetting the given dense row.

Parameters
rowThe dense row to be resetted.
Returns
void
