Method Detail

### value

    DerivativeStructure value(DerivativeStructure[] point)
                              throws MathIllegalArgumentException

  Compute the value for the function at the given point.

  Parameters:
    `point` - Point at which the function must be evaluated.
  Returns:
    the function value for the given point.
  Throws:
    `MathIllegalArgumentException` - if `point` does not fulfill functions constraints (wrong dimension, argument out of bound, or unsupported derivative order for example)
