30 Oct 2014 Free-knot spline approximation Least squares approximation of 1D data using free-knots spline Author: Bruno Luong

To Fasta:

Yes for k=1; the gradient wrt knots are dirac like, and the gradient method used by here cannot handle it correctly.

Yes, it's a major work to extend to 2D.

07 Oct 2014 TabPanel Constructor v2.8 (2010) TabPanel Constructor offers the easiest way for creating of tabpanels in MATLAB! Author: Elmar Tarajan

Under V2014B the table label is hidden by other objects. The work around it to add this piece of code at the opening of the GUI

p = handles.TBP_TabPanelContainer(2);
h = get(p,'Children');
ispanel= strcmp(get(h,'Type'),'uipanel');
set(p,'Children', [h(~ispanel) h(ispanel)]);

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

20 Nov 2014 FFT-based convolution Discrete convolution using FFT method Author: Bruno Luong AP

This is what I experimented with the code.

>> tic,A = convnfft(rand(300,300,300), ones(5,5,5), 'same');toc
Elapsed time is 8.061082 seconds.

>> tic,A = convn(rand(300,300,300), ones(5,5,5), 'same');toc
Elapsed time is 2.085360 seconds.

>> 8.061082/2.085360
ans =
3.8656

04 Nov 2014 Free-knot spline approximation Least squares approximation of 1D data using free-knots spline Author: Bruno Luong fasfa

Thank you, any possible modification to make it work for k=1? if not, do you know any other method for constant piece wise approximation?

02 Nov 2014 Min/Max filter Multidimensional non-linear min/max filtering Author: Bruno Luong seongjin

So far, this is the fastest that I know. Thank you.
