Hi Martin,

Just my two cents....

any true polynomial shape can be deconstructed into basic shapes. Squares
and triangles.
for any separate shape you will have all corner points
You would have to establish outside boundary of each shape
Then you could see if a point is out, on or in the shape.

But I think it would be a hell of a programming job to accomplish this, and
perhaps would look for an outside way to generate required result.

perhaps the customfunction at http://www.briandunning.com/cf/1260 can be of
any help?
Also the FMP function Combination(setSize;numberOfChoices) migth be usefull
To visually reproduce in/out you migth plot a radar-graph with the xmChart
plug in, and visually verify the result
also: http://polynomial-regression.software.informer.com/
also http://www.fusioncharts.com/PowerCharts/ has a plug-in to work with
plynomial graphs, but these return only visual results. I gather you want a
True/False

you aren't trying to solve a 'does it fit' problem are you? (see
http://www.dbmonster.com/Uwe/Forum.a...in-a-Container)

Well it has become two and a half cents rather.......

Hou je goed / keep well,

Ursus

Hi all,

do you know of any solutions within FMP to calculated whether a records
value (x,y coordinates) is inside or outside a given polynomial shape?

It's straight forward to check for min/max values, but it seems to be
rather complicated to mimic an inside/outside calculation within FMP!?

Thanks,
Martin
