Constructor & Destructor Documentation

functor_cost_fnc()

functor_cost_fnc::functor_cost_fnc	(	Matrix	matrix_in,
		tbb::combinable< double > *	partial_cost_functions_in
	)

Constructor of the class.

Parameters

matrix_in	Arry containing the input matrix
partial_cost_functions_in	Preallocated array storing the calculated partial cost functions.

Returns

Returns with the instance of the class.

Parameters

matrix_in	Arry containing the input matrix
matrix_size_in	The number rows in the matrix.
partial_cost_functions_in	Preallocated array storing the calculated partial cost functions.
partial_cost_fnc_num_in	The number of partial cost function values (equal to the number of distinct submatrix products.)

Returns

Returns with the instance of the class.

Member Function Documentation

operator()()

void functor_cost_fnc::operator()

(

tbb::blocked_range< int >

r

)

const

Operator to calculate the partial cost function derived from the row of the matrix labeled by row_idx.

Parameters

r	A TBB range labeling the partial cost function to be calculated.

Definition at line 509 of file N_Qubit_Decomposition_Cost_Function.cpp.

print()

void logging::print ( const std::stringstream &  sstream, int  verbose_level = 1  ) const

inherited

Call to print output messages in the function of the verbosity level.

Parameters

sstream	The stringstream input to store the output messages.
verbose_level	Integer input. High level means write more to the standart output, 0 means write nothing. The default value is set to 1.

Definition at line 55 of file logging.cpp.

set_debugfile()

void logging::set_debugfile ( std::string  debugfile )

inherited

Call to set the debugfile name.

Parameters

debugfile

String variable. Set the debugfile name.

inherited

Call to set the verbose attribute.

Parameters

verbose_in

Integer variable. Set the number to specify the verbosity level for output messages.
