@mark: Thank you. I have been sweeping the code for dependencies today, and believe they are all gone.

@matthew: We have strived to make the toolbox free of dependencies. There may still be some dependencies in the demos, but there really should not be any in the toolbox itself.

If you stumble across some then please let us know where exactly, and we will try to remove them.

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.

Nice, useful and compact code! It would be nice if i could give it a list of handles to put in the legend.

Nice. There is also the built-in function findpeaks from the signal processing toolbox:

@mohammad: The code does do MLR. Here's an example with multiple predictors:

X=randn(100,4);
y=X*[4 2 4 1]'+randn(100,1)*.2;
[p,stats]=quantreg(X,y,.9);

I invite all of you to contribute to the development of this code.

(I would like the code to support writing, and it would also be great if it automatically could insert NaNs and perhaps convert units according to the attributes for a variable).
