ne
ne( QDataSet ds1, QDataSet ds2 ) → QDataSet
element-wise not equal test. 1.0 is returned where elements are not equal.
Fill is returned where either measurement is invalid.
Parameters
ds1 - a QDataSet
ds2 - a QDataSet
Returns:
a QDataSet

ne( Object ds1, Object ds2 ) → QDataSet
negate
negate( QDataSet ds1 ) → QDataSet
return a dataset with each element negated.
If units are specified, Units must be ratiometric units, like "5 km"
or dimensionless, and not ordinal or time location units.
Parameters
ds1 - a QDataSet
Returns:
a QDataSet

negate( Object ds1 ) → QDataSet
neighborFill
neighborFill( QDataSet ds ) → QDataSet
fill in the missing values by copying nearest data points. All data
in the result will be copies of elements found in the result, but no
regard is given to how far a point is shifted. This was
motivated by supporting fill in median.
Parameters
ds - a QDataSet
Returns:
dataset that does not contain fill.

normalize
normalize( QDataSet ds ) → QDataSet
normalize the data so that the max is 1, where we normalize by the biggest
value, so that the maximum is one.
Parameters
ds - a QDataSet
Returns:
dataset with the same geometry as ds.

normalize( QDataSet ds, int dim ) → QDataSet
not
not( QDataSet ds1 ) → QDataSet
element-wise logical not function. non-zero is true, zero is false.
Parameters
ds1 - a QDataSet
Returns:
a QDataSet
