Data Analysis
Data Analysis Documentation
The MATLAB 7.1 documentation includes a new Data Analysis book that describes how
to use MATLAB functions and tools for common data-analysis tasks:
• Plotting
• Filtering
• Interpolation
• Descriptive statistics
• Correlation
• Data fitting using linear regression
• Fourier analysis
• Time-series analysis
Some of the content in Data Analysis is incorporated from the Mathematics and Graphics
books, such as data plotting, descriptive statistics, data fitting, and Fourier analysis. All
information about time-series analysis is new.
Time-Series Analysis
You can analyze time-series data using the new timeseries and tscollection objects
and methods, as well as the Time Series Tools graphical user interface. This new
functionality supports the following:
• Representation for univariate or multivariate MATLAB time series and Simulink
logged-signals data
• Built-in management of time units
• Removal or interpolation of missing data
• Resampling of data
• Arithmetic operations for timeseries objects
• Synchronization of time series
Note Due to reported instabilities on the Linux 64 platform, you must manually enable
the Time Series Tools feature before starting Time Series Tools.
