Below provides some food for thought, please consult the appropriate help topics for other options. >>> import numpy as np >>> unique = np.arange(100) >>> unique = unique.reshape(10,10) >>> unique array([[ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9],        [10, 11, 12, 13, 14, 15, 16, 17, 18, 19],        [20, 21, 22, 23, 24, 25, 26, 27, 28, 29],        [30, 31, 32, 33, 34, 35, 36, 37, 38, 39],        [40, 41, 42, 43, 44, 45, 46, 47, 48, 49],        [50, 51, 52, 53, 54, 55, 56, 57, 58, 59],        [60, 61, 62, 63, 64, 65, 66, 67, 68, 69],        [70, 71, 72, 73, 74, 75, 76, 77, 78, 79],        [80, 81, 82, 83, 84, 85, 86, 87, 88, 89],        [90, 91, 92, 93, 94, 95, 96, 97, 98, 99]]) >>> import arcpy >>> out_raster = arcpy.NumPyArrayToRaster(unique) >>> out_raster.save("c:/temp/testRaster") >>> ...

You might have bigger problems ... 1/2 isn't 0.2 But I suspect you did 1/5, in any event, you performed integer division if one or both of your values weren't floating point ie, in Python >>> print 1/5 0 >>> print 1/5.0 0.2 >>> ... View more

references to literature would help... some issues... creating the convex hull (CH) (aka convex polygon) and removing the hull points  and re-doing the analysis will fail in almost all cases ... as will buffering negatively by 5% of the area not fairly represent your analysis, so in short could you provide some visuals or some description which would account for the general situations ie your clustering consists of 4 points, 5 points with one outlier etc etc.  it may be the clustering algorithm that you are interested in rather than the CH ...

Is suspect that your latter fails since you are passing an array and not an array of point objects to the polygon class.  follow the example in the help file http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Polygon/000v000000n1000000/ and in the previous discussion on creating polygons with donuts in them http://forums.arcgis.com/threads/18985-Bug-Creating-polygons-with-holes-using-Arcpy?p=61005&posted=1#post61005 ...

As a suggestion, which probably doesn't apply to beta, I never use the built-in help but the online help since it separates ArcMap from the help and it is uptodate...for future consideration...in fact esri should consider online help as the first goto, then if no web access, then the online help ...
