A pdf of the paper and a zip of sample data are included for seascorr. 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.Īmong the files included is seascorr, which has been published in Computers & Geosciences. Matlab also has data types called "cells" and "structures", which are best found out about by reading the Matlab documentation. (3x1)i column vector (3 elements) of integers The best way of describing this code is by way of example: Matlab toolboxes required (e.g., signal processing)Īmong other things, the comment secti0ons defines the input and output arguments.UW Functions Called (other functions I wrote).extended description of what the function does.My opening comments are organized as follows: I suggest you read the comment section at the beginning of any function before using the function. To find out what's in the Tree-Ring Matlab Toolbox, check out the function list,, which give a brief description of what the function does. But due to time constraints, I cannot promise anything more than grudging cooperation in updating or correcting functions when I'm in the mood. I welcome any comments on the functions in the function list. I require no acknowledgement of the source. Alternatively, move your data to the dedicated folder and run programs with that folder as the current working directory. 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. I recommend keeping those functions by themselves in a dedicated folder. I have zipped these into a file File_pooled.zip, which you should unzip into a directory on your Matlab path. The best method to be sure you don't call an "unknown" function is to download the whole set of Tree-Ring Toolbox functions. My functions usually call on other utility functions I wrote. To use the Tree-Ring Toolbox, you must its functions in a directory on your Matlab path. Some functions requre statistics, signal processing or spline toolboxes. The comment section of each function lists which toolboxes are required. Depending on which functions you intend to use, you may also need to have one or more "Matlab toolboxes" (e.g., statistics) installed. The functions may not work on older versions. I use the University of Arizona Matlab site license, which has the most recent Matlab release. To use the Tree-Ring Toolbox, you must have Matlab installed on your computer or network. For example, the function crn2vec2 reads an ITRDB-formatted ".crn" file and returns the site chronology, years, and sample size as matlab vectors. The "Tree-Ring Toolbox" is not a commercially available Matlab toolbox, but is a collection of Matlab functions I have written to do various tasks in tree-ring analysis. Toolboxes are available for signal processing, mapping, image processing, neural networks, statistics, and many other topics. Matlab "toolboxes" with specialized functions can also purchased from The MathWorks, Inc. The basic Matlab package has many functions generally useful for tree-ring studies.
