exprVariables()

std::vector< std::string > Aqua::Tokenizer_muparser::exprVariables

(

const std::string

eq

)

Get the list of variables used on an mathematical expression.

Parameters

eq	Math expression to solve.

Returns

List of variable names

isVariable()

bool Aqua::Tokenizer_muparser::isVariable ( const std::string name )

protected

Checks if a variable has been registered.

Parameters

name	Name of the variable

Returns

true if already exist a variable with the given name, false otherwise.

registerVariable()

template<typename T>

bool Aqua::Tokenizer_muparser::registerVariable ( const std::string name, T value )

inline

Register a variable.

In case that the variable already exist, it will be modified.

The registered variables can be used later in the expression to be evaluated.

Parameters

name	Name of the variable.
value	Value of the variable.

Returns

true if the variable already exists, false otherwise.

Here is the call graph for this function:

solve()

template<typename T = float>

T Aqua::Tokenizer_muparser::solve ( const std::string eq )

inline

Solve a math expression.

Parameters

eq	Math expression to solve.

Returns

Expression value, 0.0 if the evaluation failed (it will be reported by terminal).

Here is the call graph for this function:

variable()

template<typename T = float>

T Aqua::Tokenizer_muparser::variable ( const std::string name )

inlineprotected

Returns a variable value.

Parameters

name	Name of the variable

Returns

The Value of the variable, or 0.0 if the variable cannot be found.
