<h2>Requirements</h2><br>
To use the Tree-Ring Toolbox, you must have Matlab installed on your computer or network. I use the University of Arizona Matlab site license, which has the most recent Matlab release. The functions may not work on older versions. Depending on which functions you intend to use, you may also need to have one or more "Matlab toolboxes" (e.g., statistics) installed. The comment section of each function lists which toolboxes are required. Some functions requre statistics, signal processing or spline toolboxes.<P>

The functions may not work on older versions. Depending on which functions you intend to use, you may also need to have one or more Matlab "toolboxes" installed. The comment section of each function lists which toolboxes are required. I currently have 14 toolboxes installed, but you will not need most of those. Most commonly, my functions make use of these toolboxes: Curve Fitting, Statistics and Machine Learning, Signal Processing, System Identification. <P>

To use the Tree-Ring Toolbox, you must its functions in a directory on your Matlab path. My functions usually call on other utility functions I wrote. The best method to be sure you don't call an "unknown" function is to download the whole set of Tree-Ring Toolbox functions. I have zipped these into a file <a href="http://www.ltrr.arizona.edu/~dmeko/outbox/Files_pooled.zip">File_pooled.zip</a>, which you should unzip into a directory on your Matlab path. I recommend keeping those functions by themselves in a dedicated folder. Put that folder first on your Matlab path, so that no other functions you might have by the same name, or not obsolete versions of the same function, are used. Alternatively, move your data to the dedicated folder and run programs with that folder as the current working directory.

I distribute these function freely. I require no acknowledgement of the source. Go ahead and modify them as you wish. I welcome any comments on the functions in the <a href="#fcnlist">function list</a>. But due to time constraints, I cannot promise anything more than grudging cooperation in updating or correcting functions when I'm in the mood. <P>

Matlab also has data types called "cells" and "structures", which are best found out about by reading the Matlab documentation. My code for cells uses braces. For example,
the code below indicates a 1 x 3 "cell" variable containing a 2x2 integer matrix, a 1x5 character string and a 1x10 row vector of real numbers.
