public void contour(double[][] d,
                    int ilb,
                    int iub,
                    int jlb,
                    int jub,
                    double[] x,
                    double[] y,
                    int nc,
                    double[] z)

contour is a contouring subroutine for rectangularily spaced data It emits calls to a line drawing subroutine supplied by the user which draws a contour map corresponding to real*4data on a randomly spaced rectangular grid. The coordinates emitted are in the same units given in the x() and y() arrays. Any number of contour levels may be specified but they must be in order of increasing value.

Parameters:

d - - matrix of data to contour

ilb - - index bounds of data matrix

iub - - index bounds of data matrix

jlb - - index bounds of data matrix

jub - - index bounds of data matrix The following two, one dimensional arrays (x and y) contain the horizontal and vertical coordinates of each sample points.

x - - data matrix column coordinates

y - - data matrix row coordinates

nc - - number of contour levels

z - - contour levels in increasing order.
