Method Details

getCompiler

public static TurboExpressionEvaluator getCompiler(MathExpression me)

Intelligently selects and returns the best Turbo engine for the expression.

Parameters:

me - The MathExpression

Returns:

A TurboExpressionEvaluator that can be used to evaluate expressions at turbo speed

getCompiler

public static TurboExpressionEvaluator getCompiler(MathExpression me,
 boolean useWideningVarsPassing)

Parameters:

me - The root MathExpression

useWideningVarsPassing - If true, will create a turbo evaluator that uses widening to pass variables, else it uses an array based approach. If you are not sure, if your expression has more than 63 unique variables, definitely set this variable to false. Else test with true or false for your particular expression and see which has higher performance. They usually give performances within 1-20ns of each other.

Returns:

A TurboExpressionEvaluator that can be used to evaluate expressions at turbo speed

createMatrixLeaf

public static MethodHandle createMatrixLeaf(String symbol)
