Class RandomPiecewiseLinear

java.lang.Object
edu.cmu.tetrad.search.utils.RandomPiecewiseLinear
public class RandomPiecewiseLinear extends Object
Represents a piecewise linear function with randomly generated breakpoints and values. This class allows computation of values at any x within or outside the defined range of breakpoints.

    • RandomPiecewiseLinear

      public RandomPiecewiseLinear(int numPoints, double minX, double maxX)
      Constructs a RandomPiecewiseLinear instance. This method generates a piecewise linear function based on the specified number of points, with x-coordinates randomly distributed within a specified range and y-coordinates randomly assigned in the range [-2, 2].
      Parameters:
      numPoints - the number of breakpoints to generate for the piecewise linear function; must be greater than or equal to 2
      minX - the minimum value in the range for the x-coordinates of the breakpoints
      maxX - the maximum value in the range for the x-coordinates of the breakpoints
      Throws:
      IllegalArgumentException - if numPoints is less than 2

  • Method Details

    • main

      public static void main(String[] args)
      The main method serves as the entry point of the program. It demonstrates the usage of the RandomPiecewiseLinear class by creating an instance and computing the values of a piecewise linear function at various points within a specified range. The results are printed to the console with formatted output for each computed value.
      Parameters:
      args - the command-line arguments, which are not used in this implementation

    • computeValue

      public double computeValue(double x)
      Computes the value of the piecewise linear function for a given x-value. If the x-value falls outside the defined range of xPoints, the method performs extrapolation. Otherwise, it determines the appropriate segment and performs interpolation.
      Parameters:
      x - the x-coordinate for which to compute the corresponding y-value
      Returns:
      the computed y-value corresponding to the given x-coordinate
      Throws:
      IllegalStateException - if the provided x-value cannot be handled due to an unexpected condition
