      • normalizationParameter

        public String normalizationParameter()
        Description copied from interface: IFunction
        Returns the name of the normalization parameter if the function has one.
        Specified by:
        normalizationParameter in interface IFunction
        The name of the normalization parameter.null if no such parameter is available
      • codeletString

        public String codeletString()
        Description copied from interface: IFunction
        String describing the metatype and implementation of the function. Generic format of the string: codelet:TYPE:LOCATION TYPE part contains only a 'typename' string which is a metatype identifier (used in plugins and catalogues) LOCATION may be: 'file', 'verbatim', or 'catalogue' Detailed description: codelet:typename - no location specified (using 'catalogue') codelet:typename:file:/filename.cpp - a c++ source file codelet:typename:file:/ - a python source file codelet:typename:file:/ - a shared library codelet:typename:catalogue - entry in a catalogue repository codelet:typename:verbatim:cpp \n - c++ source file included verbatim after \n codelet:typename:verbatim:py \n - python source file included verbatim aftern \n Comments: file:/filename is a relative path to $AIDA_FUNCTION_DEFAULT_DIR file://filename is an absolute path Examples: codelet:G:catalogue codelet:userSinus:verbatim:cpp \n { return sin(x); }
        Specified by:
        codeletString in interface IFunction
      • dimension

        public int dimension()
        Description copied from interface: IFunction
        Dimensionality of the domain space.
        Specified by:
        dimension in interface IFunction
      • gradient

        public double[] gradient(double[] values)
        Description copied from interface: IFunction
        Gradient of the function. The result is valid only if providesGradient()==true. Otherwise the result is some default (empty) vector.

        gradient in interface IFunction
      • indexOfParameter

        public int indexOfParameter(String str)
        Description copied from interface: IFunction
        Return -1 if parameter not found (name undefined). Leave it because there are use cases - some users prefer to use numbers.
        Specified by:
        indexOfParameter in interface IFunction
      • isEqual

        public boolean isEqual(IFunction iFunction)
        Description copied from interface: IFunction
        Compare if functions are the same. PENDING: define exactly what it means ;)
        Specified by:
        isEqual in interface IFunction
      • parameterNames

        public String[] parameterNames()
        Description copied from interface: IFunction
        Names of paramaters. Names should be unique. Case-insensitive for comparison. Case-sensitive for storage and output. All or several names may be left blank "" if the implementation does not want to provide them.
        Specified by:
        parameterNames in interface IFunction
      • parameters

        public double[] parameters()
        Description copied from interface: IFunction
        Retrieve current vector of parameters.
        Specified by:
        parameters in interface IFunction
      • providesGradient

        public boolean providesGradient()
        Description copied from interface: IFunction
        Determine whether function is able to compute gradient.
        Specified by:
        providesGradient in interface IFunction
      • title

        public String title()
        Description copied from interface: IFunction
        Get the Function's title.
        Specified by:
        title in interface IFunction
        The Function's title.
      • value

        public double value(double[] values)
        Description copied from interface: IFunction
