Method Detail

evaluate

public IExpr evaluate(IAST ast)

Description copied from class: AbstractFunctionEvaluator

Symbolic evaluation of a function. ast.get(0) contains the head (i.e. the function symbol) of this abstract syntax tree (AST). ast.get(1) to ast.get(n) contains the first to n-th argument of the function.
If necessary use the methods from the Validate class to check the number or types of arguments in the evaluate method.
Note: if the symbolic evaluation isn't possible or no result is found the evaluate method returns with a null value without throwing an exception!

Specified by:

evaluate in interface IFunctionEvaluator

Specified by:

evaluate in class AbstractFunctionEvaluator

Parameters:

ast - the abstract syntax tree (AST) which should be evaluated

Returns:

the evaluated object or null, if evaluation isn't possible

Validate

evaluateArg1

public IExpr evaluateArg1(IExpr arg1)

numericEval

public IExpr numericEval(IAST ast)

Description copied from class: AbstractFunctionEvaluator

Numeric evaluation of a function. ast.get(0) contains the head (i.e. the function symbol) of this abstract syntax tree (AST). ast.get(1) to ast.get(n) contains the first to n-th argument of the function.
If necessary use the methods from the Validate class to check the number or types of arguments in the evaluate method.

Specified by:

numericEval in interface IFunctionEvaluator

Overrides:

numericEval in class AbstractFunctionEvaluator

Parameters:

ast - the abstract syntax tree (AST) which should be evaluated

Returns:

the evaluated object or null, if evaluation isn't possible

numericEvalD1

public IExpr numericEvalD1(Num arg1)

Evaluate this function for one double argument

Parameters:

arg1 - a double number

Returns:

numericEvalDC1

public IExpr numericEvalDC1(ComplexNum arg1)

Evaluate this function for one double complex argument

Parameters:

arg1 - a double complex number

Returns:

numericEvalArg1

public IExpr numericEvalArg1(IExpr arg1)
