11 Aug 2014 Dividing values into equal sized groups Distribute values, as evenly as possible, over quantile rank groups. Author: Mohammad Rawashdeh

Great function to randomly break ties in ranks. Can be used as
y=quantileranks(x,numel(x));

16 Jul 2014 Proportional Venn Diagrams Draws a venn diagram for two or three sets with proportional areas. Author: Jeremy Heil

Does not show anything if there is no overlap. I'd like to see separated circles of size proportional to number of elements in them. Please don't make a new figure by default. Also how to make several diagrams have the same (or similar) resolution? I'm creating multiple diagrams on the same figure in subplots. Another suggestion - it would be nice to be able to customize colors and labels (position, font, etc).

Another suggestion. The vertex labels should be at 100%, not 0%.

02 Sep 2013 Ternplot Plots ternary phase data on a ternary phase diagram. Author: Carl Sandrock

Great function! -1 because labeling with gname cannot be used due to data sorting. Make the sort optional and/or return the sorting index.

29 Aug 2013 Round with significant digits Rounds towards the nearest number with N significant digits. Author: François Beauducel

Great function. I should find it earlier.

Will, it's a precision problem of floating point arithmetic. Try:
3.55/0.1-35.5
ans =
-7.105427357601e-15
This little number trigger the balance. I think it's hard to overcome.

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 ?
Jérôme

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!
