PWLExpression

  • public class PWLExpression
extends FormulaExpression
    A class that represents a piecewise linear function.
    Since:
    43.00

    • Constructor Detail

      • PWLExpression

        public PWLExpression​(Variable argument,
                     double[] breakX,
                     double[] breakY)
        Create a new piecewise linear function invocation. The constructor will sort the breakpoints lexicographically.
        Parameters:
        argument - Variable at which the function should be evaluated.
        breakX - x coordinates of breakpoints.
        breakY - y coordinates of breakpoints.
        Since:
        43.00

      • PWLExpression

        public PWLExpression​(Variable argument,
                     PwlBreakpoint... points)
        Create a new piecewise linear function invocation. The constructor will sort the breakpoints lexicographically.
        Parameters:
        argument - Variable at which the function should be evaluated.
        points - The breakpoints for the new PWL.
        Since:

      • PWLExpression

        public PWLExpression​(int argument,
                     double[] breakX,
                     double[] breakY)
        Create a new piecewise linear function invocation. The constructor will sort the breakpoints lexicographically.
        Parameters:
        argument - Column index at which the function should be evaluated.
        breakX - x coordinates of breakpoints.
        breakY - y coordinates of breakpoints.
        Since:
