File Information
Description

A key challenge with the growing volume of measured data in the energy sector is the preparation of the data for analysis. This challenge comes from data being stored in multiple locations, in multiple formats, and with multiple sampling rates. This demonstration considers the collection of time-series data sets from multiple sources including Excel files, SQL databases, and data historians. Techniques for preprocessing the data sets are shown, including synchronizing the data sets to a common time reference, assessing data quality, and dealing with bad data. It is then shown how subsets of the data can be extracted to simplify further analysis.

Required Products Curve Fitting Toolbox
Statistics and Machine Learning Toolbox
System Identification Toolbox
MATLAB
MATLAB release MATLAB 8.0 (R2012b)
Other requirements SQL database server if you want to load data from a database

There are lots of interesting commands to copy. It provides good examples of how to handle and analyze time series.
