Get Organized with Eigenvector's DSO

The dataset object is a MATLAB® object written to be applicable to any data which requires storing axillary information along with the data itself. In order to facilitate data set handling, Eigenvector created a standard object, the DATASET Object (DSO). This innovative application provides a standard way to associate all the parts of a data set that go together, including the sample and variable labels, class variables, time and wavelength axes, etc. When added to a MATLAB installation, DataSet creates a new object that integrates all the separate components associated with a data set into a single variable in the MATLAB workspace.

An example of the MATLAB command window after the DataSet files have been installed is shown below. Data consisting of three different variables has been loaded into the workspace. These include the data matrix dat, sample labels names and variable labels vars. This data can be combined into a single data object h using the commands shown. When displayed, the separate parts of the data are listed. (The data object should look familiar to those who have been using MATLAB structures.)

DSO Freely Available

Eigenvector Research is making the DataSet object freely available and hopes that MATLAB users everywhere will use it when writing routines that are data intensive. Existence of the object will greatly enhance the exchange of data sets, the translation of data sets between file types (such as JCAMP) and the handling of data sets within MATLAB. Of course, the PLS_Toolbox takes full advantage of the DataSet object and also provides several data import routines.Comments and ideas would be especially appreciated.

Product support is available through the Eigenvector helpdesk.
