24 Jun 2014 Voronoi Sphere Compute voronoi's diagram of points on the 2-sphere Author: Bruno Luong

To Eric: the output (K) _is_ sorted as the input seeds.

10 Jun 2014 Consecutive vector spliter Partition an input vector into smaller series of subvectors of consecutive elements Author: Bruno Luong

Monotonic

SplitVec(a, @(v) [0; diff(v(1:end-1)).*diff(v(2:end))<0])

09 Jun 2014 IritPolynomialSolver.zip A matlab interface for the IRIT multivariate solver of systems of nonlinear polynomial equations. Author: Jonathan Mizrahi

This would be very useful package
Unfortunately it requires symbolic package and the source code for MEX files (only for PC) is not provided, It would be useful of draft of the scientific papers are provided

05 Jun 2014 Vectorized FIND with 'FIRST' option Find the first non-zero element(s) along row/column - or any other dimension Author: Bruno Luong

@Cullen, please ask Mac developer forum. It is odd that an integer 32 bits is not 4 bytes. Something must be very wrong,

01 Jun 2014 Min/Max selection Search for k smallest or largest elements in the array Author: Bruno Luong

@JUNBO please replace line #19 of minmax_install.m with this:

if ispc() && datenum(version('-date')) < datenum('January 11, 2014')

Hi
Im trying to build a large FE model with this package but i dont get any advantage on the speed.

shuangou ren how exactly do u use it one FE assemblage

I am running 2014a on a machine with 192Gb of RAM and 20 cores. I am trying to convolute two vectors, one with 3,060,663 elements, the other with 693. The built-in conv took 0.06 seconds. convnfft filled the memory and then crashed the machine.

29 Aug 2014 Consecutive vector spliter Partition an input vector into smaller series of subvectors of consecutive elements Author: Bruno Luong Shen, Xinyi

This is a great function that I am looking for.
However, it would be more perfect if
1. the array can be unsorted.
2. the indices can be returned
For example, [s,i] = SplitVec([1 2 1 3 2 1])
where
s={[1 1 1],[2,2],[3]}
i={[1 3 6],[2,5],[4]}
I do not know if it is possible

I downloaded your code and tried to install launching the installation function from Matlab command line. I use a Mac running Maverick (10.9.4)
I got the following error that I am copying in the following.
I verified that clang is installed:
f4230:~ mauede$ which clang
/usr/bin/clang
I would greatly appreciate your help.Thank you so much.
Regards,
Maura Monville
