Description copied from interface: DataSetRebinner

create a new QDataSet in a rank 2 table with x and y tags described by x and y.

Specified by:

rebin in interface DataSetRebinner

Parameters:

ds - The input dataset, either a rank 2 or rank 3 dataset. Note this may include rank 1 dataset and rank 2 bundles at some point.

ddX - describes the column labels. (Note this may become a QDataSet at some point).

ddY - describes the row labels.

ddZ - describes the Z space for the rebinning, in particular log.

Returns:

a rank 2 QDataSet with the given rows and columns.

Throws:

java.lang.IllegalArgumentException

DasException
