Function Documentation

convert_expression_map_to_basic_map()

SymEngine::map_basic_basic Differentiation::SD::Utilities::convert_expression_map_to_basic_map

(

const SD::types::substitution_map &

substitution_map

)

Convert a map of Expressions to its SymEngine counterpart.

convert_basic_map_to_expression_map()

SD::types::substitution_map Differentiation::SD::Utilities::convert_basic_map_to_expression_map

(

const SymEngine::map_basic_basic &

substitution_map

)

Convert to a map of Expressions from its SymEngine counterpart.

convert_expression_vector_to_basic_vector()

SymEngine::vec_basic Differentiation::SD::Utilities::convert_expression_vector_to_basic_vector

(

const SD::types::symbol_vector &

symbol_vector

)

Convert a vector of Expressions to its SymEngine counterpart.

convert_basic_vector_to_expression_vector()

SD::types::symbol_vector Differentiation::SD::Utilities::convert_basic_vector_to_expression_vector

(

const SymEngine::vec_basic &

symbol_vector

)

Convert to a vector of Expressions from its SymEngine counterpart.

convert_basic_pair_vector_to_expression_pair_vector()

std::vector<std::pair<Expression, Expression> > Differentiation::SD::Utilities::convert_basic_pair_vector_to_expression_pair_vector

(

const SymEngine::vec_pair &

symbol_value_vector

)

Convert to a vector of pairs of Expressions from its SymEngine counterpart.

extract_symbols()

SD::types::symbol_vector Differentiation::SD::Utilities::extract_symbols

(

const SD::types::substitution_map &

substitution_values

)

Extract the symbols (key entries) from a substitution map.

Note

It is guaranteed that the order of extraction of data into the output vector is the same as that for extract_values(). That is to say that the unzipped key and value pairs as given by extract_symbols() and extract_values() always have a 1:1 correspondence.

extract_values()

template<typename NumberType , typename ExpressionType = SD::Expression>

std::vector<NumberType> Differentiation::SD::Utilities::extract_values

(

const SD::types::substitution_map &

substitution_values

)

Extract the values from a substitution map. The value entries will be converted into the NumberType given as a template parameter to this function via the ExpressionType.

Note

It is guaranteed that the order of extraction of data into the output vector is the same as that for extract_symbols(). That is to say that the unzipped key and value pairs as given by extract_symbols() and extract_values() always have a 1:1 correspondence.

print_substitution_map()

template<typename StreamType >

StreamType& Differentiation::SD::Utilities::print_substitution_map	(	StreamType &	stream,
		const SD::types::substitution_map &	symbol_value_map
	)

Print the key and value pairs stored in a substitution map.
