You may try tocall Boolean.TRUE

comment Calculating a potential function using the finite element method
@MarkMcClure yes you are right. It is also mentioned in other discussions that some parameters are ignored. However, by discretizing region as in Q 3 {0, 0} problem disappears.

comment Calculating a potential function using the finite element method
problem 2 and 3 can be corrected by using DiscretizeRegion. dis = DiscretizeRegion[reg] and than mesh = ToElementMesh[dis, MaxCellMeasure -> 0.0005, "MaxBoundaryCellMeasure" -> 0.01];

comment Object separation from a 2.5D surface
@zeckra Instead of dealing with geometric models how about defining problem as optimization task and fitting biggest blob or sphere? If I am not mistaken MichaelE2 has related nice solution for 2d circle.

Is there any particular reason you didn't put "m" in the first one and what is the expected result?

comment Proving (self) similarity with Mathematica - Reccurrence Plots, Similarity Plots etc
May be you can use fractal dimensions to measure the similarities. Also related post might help 'Measuring fractal dimension of natural objects from digital images' but mainly for images mathematica.stackexchange.com/questions/13125/…

comment Strange behavior of `BoundaryMeshRegion`
I also think it a bug. An easy way to achieve the same result is with r = BoundaryDiscretizeRegion[Cuboid[{4, 4, 4}, {6, 6, 6}]]

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard Programming wise yes there are many flexibilities in Mathematica and hard to map one by one. However, toolboxes such as image possessing, statistics, wavelets, ect. has very similar commands. It may need a lot of effort to map, but as community page one can improve and add thing as common effort. I personally think it will be quite beneficial for future 2 program users.

you may use Overlay and SetAlphaChannel Overlay[{isosurface, SetAlphaChannel[ Graphics3D[{Black, PointSize[0.05], Point[geom]}, Boxed -> False], .5]}, All, 2]

comment How to count the number of n-gons and line intersections in an image of a complete graph?
@GenericUsrnme Do you want image processing solution or graph based solution with Mathematica. you may check mathematica.stackexchange.com/questions/19546/… belisarius's solution for detecting intersection point using image processing solution. For 2d intersection detection algorithms you can check mathematica.stackexchange.com/questions/24211/… for references form this site.

comment Generating x,y coordinates for an edge detection
@nikie Overall, nice approach, but I think you need to clean shadows on the left hand side of the image to get it right size (min max includes the shadow :) ).

comment Identifying critical points of 2/3D image/cubes
@chris en.wikipedia.org/wiki/Marching_cubes is 3D, based on en.wikipedia.org/wiki/Marching_squares mentioned there. Also Azim's answer there is interesting to read. PS: Under wikipedia matlab or java codes are also available.

comment Estimate parameters of the state space model
I don't think there is single command to handle this in Mathematica. You have to use FindMinimum or FindFit command and define your own criteria to fit the data you have. The criteria should include the difference between your data and the model output by calculating the norm which you should minimize.

@rcollyer yes you are right. Before the edited version you can. But the final version might change alot and you cant cite it.
