Data Analysis, MATLAB Version 7.1 (R14SP3)

New features and changes introduced in this version are described in this section:

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.

To manually enable Time Series Tools on the LinuxLinux 64 platform, type the following at the MATLAB prompt:
