File Information
Description

ShadedCorrelationTable produces a correlation table for a set of variables, enhanced graphically with shading according to correlation values.

Upper or lower ranges of correlation values may be highlighted through the interface controls. Two methods are provided to do this: a decay function that softens shading of values of less interest, or, shading according to a discrete threshold.
 
Pearson's linear correlation coefficient is used.

Usage:

     ShadedCorrelationTable(x, xLabels);

Example:

load('demo data.mat');
ShadedCorrelationTable(data.x,data.labels);

Acknowledgements

Usercolormap and Rotate X Labels( Ax, Angle, Varargin ) inspired this file.
