moments_region_3rd moments_region_3rd MomentsRegion3rd MomentsRegion3rd (Operator)
Name
moments_region_3rd moments_region_3rd MomentsRegion3rd MomentsRegion3rd
Signature
Herror moments_region_3rd (const Hobject Regions M21 M12 M03 M30
Herror T_moments_region_3rd (const Hobject Regions M21 M12 M03 M30
Description
The operator moments_region_3rd moments_region_3rd MomentsRegion3rd MomentsRegion3rd MomentsRegion3rd M21 M21 M21 M21 m21 M12 M12 M12 M12 m12 M03 M03 M03 M03 m03 M30 M30 M30 M30 m30
Calculation:
x and y are the coordinates
of the center of a region R with the area Z.
Then the moments
wherein are
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
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 region(-array) → object HRegion HRegion Hobject
Regions to be examined.
M21 M21 M21 M21 m21 real(-array) → HTuple HTuple Htuple (real) (double ) (double ) (double )
Moment of 3rd order (line-dependent).
M12 M12 M12 M12 m12 real(-array) → HTuple HTuple Htuple (real) (double ) (double ) (double )
Moment of 3rd order (column-dependent).
M03 M03 M03 M03 m03 real(-array) → HTuple HTuple Htuple (real) (double ) (double ) (double )
Moment of 3rd order (column-dependent).
M30 M30 M30 M30 m30 real(-array) → HTuple HTuple Htuple (real) (double ) (double ) (double )
Moment of 3rd order (line-dependent).
Complexity
If Z is the area of the region the mean runtime
complexity is O(sqrt(Z)).
