Name
moments_region_central_invar moments_region_central_invar MomentsRegionCentralInvar MomentsRegionCentralInvar moments_region_central_invar
Signature
Herror moments_region_central_invar (const Hobject Regions PSI1 PSI2 PSI3 PSI4
Herror T_moments_region_central_invar (const Hobject Regions PSI1 PSI2 PSI3 PSI4
def moments_region_central_invar (regions

Description
The operator moments_region_central_invar moments_region_central_invar MomentsRegionCentralInvar MomentsRegionCentralInvar MomentsRegionCentralInvar moments_region_central_invar PSI1 PSI1 PSI1 PSI1 PSI1 psi1 PSI2 PSI2 PSI2 PSI2 PSI2 psi2 PSI3 PSI3 PSI3 PSI3 PSI3 psi3 PSI4 PSI4 PSI4 PSI4 PSI4 psi4
Calculation: Then the moments
If more than one region is passed the results are stored in tuples, the index
of a value in the tuple corresponding to the index of a region in the input.
In case of empty region all parameters have the value 0.0 if no other
behavior was set (see set_system set_system SetSystem SetSystem SetSystem set_system
Execution Information
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.
Parameters
Regions Regions Regions Regions regions regions region(-array) → object HRegion HObject HRegion Hobject
Regions to be examined.
PSI1 PSI1 PSI1 PSI1 PSI1 psi1 real(-array) → HTuple Sequence[float] HTuple Htuple (real) (double ) (double ) (double )
Moment of 2nd order.
PSI2 PSI2 PSI2 PSI2 PSI2 psi2 real(-array) → HTuple Sequence[float] HTuple Htuple (real) (double ) (double ) (double )
Moment of 2nd order.
PSI3 PSI3 PSI3 PSI3 PSI3 psi3 real(-array) → HTuple Sequence[float] HTuple Htuple (real) (double ) (double ) (double )
Moment of 2nd order.
PSI4 PSI4 PSI4 PSI4 PSI4 psi4 real(-array) → HTuple Sequence[float] HTuple Htuple (real) (double ) (double ) (double )
Moment of 2nd order.
Complexity
If Z is the area of the region the mean runtime
complexity is O(sqrt(Z)).
Result
The operator moments_region_central_invar moments_region_central_invar MomentsRegionCentralInvar MomentsRegionCentralInvar MomentsRegionCentralInvar moments_region_central_invar 2 (
H_MSG_TRUE )
if the input is not empty.
The behavior in case of empty input (no input regions available) is
set via the operator set_system('no_object_result',<Result>) set_system("no_object_result",<Result>) SetSystem("no_object_result",<Result>) SetSystem("no_object_result",<Result>) SetSystem("no_object_result",<Result>) set_system("no_object_result",<Result>) set_system('empty_region_result',<Result>) set_system("empty_region_result",<Result>) SetSystem("empty_region_result",<Result>) SetSystem("empty_region_result",<Result>) SetSystem("empty_region_result",<Result>) set_system("empty_region_result",<Result>)
