09 Jul 2014 LMFnlsq - Solution of nonlinear least squares Efficient and stable Levenberg-Marquard-Fletcher method for solving of nonlinear equations Author: Miroslav Balda

Thank you for this. I use it in imgraft.glaciology.net for optimising camera parameters and it works great. I have also used it in another project where it also delivered a massive performance boost.

28 Jan 2014 Tidal fitting toolbox fit tidal components to an observed series of sea level and use them for prediction Author: Aslak Grinsted

@janez: the reason tidalfit has larger residuals is probably that it accounts for a lineal sea level rise trend. I believe that this results in a total model that scores better in an out of sample validation.

13 Aug 2014 quantreg.m - quantile regression Quantile regression with bootstrapping confidence intervals Author: Aslak Grinsted wei

hi. just a quick question. How do we calculate the goodness of fit for quantile regression? thanks

08 Aug 2014 fftnoise - generate noise with a specified power spectrum Useful helper function for Monte Carlo null-hypothesis tests and confidence interval estimation. Author: Aslak Grinsted Danziger, Zachary

Useful and quick.

05 Jun 2014 Subaxis - Subplot Use HTML jargon for multi axis layout. Author: Aslak Grinsted Hodges, Richard

I tried the first example line (in ML 2014a):

subaxis(2,1,1,'SpacingVert',0,'MR',0);

I got an error:
Error using parseArgs (line 111)
Unknown named parameter: spacingvert

Error in subaxis (line 45)
Args=parseArgs(varargin,Args,{'Holdaxis'},{'Spacing' {'sh','sv'}; 'Padding' {'pl','pr','pt','pb'}; 'Margin' {'ml','mr','mt','mb'}});

What is wrong?

02 Jun 2014 samexaxis (nice subplots with same x axis) Makes it alot easier to make nice figures with the same x axis. Author: Aslak Grinsted Wang, David

Very useful function. One minor issue: When subplots' y axis limits are explicitly set, it tends to result in yticklabel clashes. For example,

subplot(211)
plot(randn(1,100));
set(gca,'YLim',[-3 3]);
subplot(212)
plot(randn(1,100));
set(gca,'YLim',[-4 4]);
samexaxis('xmt','off','ytac','yld',1,'box','on','join')
