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.

comment How to control the layering of graphics displayed with Show
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.

@chris Did you see stackoverflow.com/questions/263305/drawing-a-topographical-map it might be helpful.

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.

comment Circle detection using invariance kernels
@Szabolcs even the authors can't distribute on their own site. They transfer the publishing copyright to publisher. I think we are all unhappy except publishers. ..

You can not distribute the paper however you can cite and put the relevant part.

comment Large scale linear programming (Data imported from .mat file)
@user2667048 you can try imp = Import["A.mat", "LabeledData"]; AA = "A" /. imp ; BB = "B" /. imp ; x = LinearProgramming[{0, 0, -1}, AA, Flatten@BB, {{-1, 100}, {0, 100}, {0, 100}}];

comment Signal processing by means of WaveletTransform
@Sektor I think you are right as explained in the link. It may also depend on the basis function. The main problem is Mathematica does not have a function such as scale2frequency as in matlab. It may be interesting to see the complete code for future use of the forum when you have time. see the link in dsp I think OP needs similar approach in Mathematica dsp.stackexchange.com/questions/10127/…

@andy you may try 'Show[image, Graphics[{Red, Text[#1, Flatten@#2] & @@@ cenData}]]' and check mathematica.stackexchange.com/questions/18393/… for more info

comment Gram Schmidt Process for functions
@D.N.S you can try rr[x_, y_] := Piecewise[{{ff[x, y], y <= x}, {gg[x, y], x > y}}]; Orthogonalize[{{1, 1}}, rr, Method -> "GramSchmidt"]
