21 Dec 2011 Alpha shape volume Volume/area of 3D/2D alpha shape. Author: Jonas Lundgren

It looks like the algorithm unequally connects point vertically and horizontally.
Try this data, for example:
n = 1000;
k = 10;
x = linspace(0,1,n)';
y(:,1) = k*x + randn(n,1) - k/2;
y(:,2) = -k*x + randn(n,1) + k/2;
xx = [x;x];
yy = y(:);
alphavol([xx yy], 0.5, 1);
29 Nov 2011 DataTable store data in a table format that supports printing in plain text, Latex, HTML, Wiki,... Author: Paul Mattern

Paul, thank you. Sorry for the late answer, I missed your reply.
Your solution leaves spaces on both sides of the delimiter. So it's actually
0.8147<space><tab><space>0.9134 etc.
16 Nov 2011 Violin Plots for plotting multiple distributions (distributionPlot.m) Function for plotting multiple histograms side-by-side in 2D - better than boxplot. Author: Jonas

@Jonas: Thanks for the answer. May I suggest a new feature? It would be nice to draw histogram at certain direction. Currently it's only centered, but also can be left- or right- directed. All you need to change is xBase variable at line 401: 0.5 to 0 for left direction, -0.5 to 0 for right direction. For someone it's easier to understand when the distributions looks like turned histograms.

Paul, thanks for the great submission!

I don't think you need lines 448-451 since you process empty table inside the printer anyway.

I made a very simple TextFilePrinter to output the table to standard tab delimited text file. Hope you'd consider to include such functionality into the package.

06 Apr 2007 rbb3select Selects points on 3D plot using rbbox. Author: Yuri Kotliarov Kotliarov, Yuri

Here is another longtimeago comment I found in my mailbox. Sorry I was not able to test it. But it may be useful for someone.

======
Hi,

I was using your file RBB3SELECT to get coordinates of nodes from a 3D mesh. I previouly used SELECT3D (available in the FEX) but it can only return one data at time.

Your code works well except when it is used with CAMERA (cameratoolbar).

So, reading SELECT3D (from TMW), I found three non-documented properties of axes : x_RenderTransform, x_RenderOffset, x_RenderScale

I just change the line 34 from RBB3SELECT :
T=view;
with this :
T=get(gca,'x_RenderTransform');

And it seems to solve the problem.
The test file RBB3TEST is still working even if you use the cameratoolbar.

I don't tested this modification more.
But it seems to enhance your contribution.

What do you think ?

Sorry for not addressing problems for this submission for a long time. I found if you have axes with prospective mode turned on, the function returns wrong points some time.
So, I have 3 choices:
1) Check prospective mode and issue a warning
2) Force axes to prospective mode off just before selection
3) Somehow calculate projection even if prospective mode on. Currently I have no idea how to do it.
Any comments?

A great little utility. I also had problems getting the correct points. However, I was able to overcome this by always setting the axes to be uniform (n x n x n).
eg/ axis([-50 50 -50 50 -50 50 1 3]), where 1 and 3 are colour scaling.

It is good but when I am using vectors describing a point cloud the wrong points are chosen for some projections. Looks like incorrect projection or something.

Very good! I was looking for it! Thank you!
