Method Detail

contour

public static QDataSet contour(QDataSet tds,
                               QDataSet levels)

returns a rank 2 dataset, a bundle dataset, listing the points of the contour paths. The dataset will be ds[n,3] where the bundled datasets are: [x,y,z] and where DEPEND_0 indicates the step number. Jumps in the step number indicate a break in the contour.

Parameters:

tds - the rank 2 table dataset

levels - the rank 1 levels

Returns:

rank 2 bundle of x,y,z where DEPEND_0 indicates the step number.

                               Datum level)

returns a rank 2 dataset, a bundle dataset, listing the points of the contour paths. The dataset will be ds[n,3] where the bundled datasets are: [x,y,z] and where DEPEND_0 indicates the step number. Jumps in the step number indicate a break in the contour.

Parameters:

tds - the rank 2 table dataset

level - the level

Returns:

rank 2 bundle of x,y,z where DEPEND_0 indicates the step number.
