Class DSFactory.DSField

    • Method Detail

      • getZero

        public DerivativeStructure getZero()
        Get the additive identity of the field.

        The additive identity is the element e0 of the field such that for all elements a of the field, the equalities a + e0 = e0 + a = a hold.

        Specified by:
        getZero in interface Field<DerivativeStructure>
        Returns:
        additive identity of the field
      • getOne

        public DerivativeStructure getOne()
        Get the multiplicative identity of the field.

        The multiplicative identity is the element e1 of the field such that for all elements a of the field, the equalities a × e1 = e1 × a = a hold.

        Specified by:
        getOne in interface Field<DerivativeStructure>
        Returns:
        multiplicative identity of the field
      • getPi

        public DerivativeStructure getPi()
        Get the Archimedes constant π.

        Archimedes constant is the ratio of a circle's circumference to its diameter.

        Returns:
        Archimedes constant π
