    • dim

      protected final int dim
      Dimension of points to be interpolated.

    • n

      protected final int n
      Number of points provided in a matrix as a basis for interpolation.

    • pts

      protected final com.irurueta.algebra.Matrix pts
      Matrix containing points to interpolate from. Each row contains one point. Matrix will have n points (rows) having a dimension (columns) equal to dim.

    • pi

      protected final double[] pi
      ith point to make comparisons.

      protected BaseRadialBasisFunctionInterpolator(com.irurueta.algebra.Matrix ptss)
      Constructor.
      Parameters:
      ptss - Matrix containing points to interpolate from. Each row contains one point. Matrix will have n points (rows) having a dimension (columns) equal to dim.

  • Method Details

    • interpolate

      public abstract double interpolate(double[] pt)
      Returns the interpolated function value at a dim-dimensional point pt.
      Parameters:
      pt - dim-dimensional point where interpolation must be computed.
      Returns:
      result of interpolation.
      Throws:
      IllegalArgumentException - if provided point has an invalid length.

    • rad

      protected double rad(double[] p1, double[] p2)
      Computes the euclidean distance between two points.
      Parameters:
      p1 - first point.
      p2 - second point.
      Returns:
      euclidean distance.
