Fourier Analysis

Standard GLCM textural analysis often doesn't give good results unless a large number of global classes are used (and using a large number of classes brings other problems). Using local classes helps, but the results are sensitive to noise. This program uses unweighted area sampling to vastly...

This is the source code and script from the case study presented during the Data Analysis Webinar on 4/24/03 (archived at http://www.mathworks.com/cmspro/online/5102/req.jsp?13727). The case study demonstrates how several MATLAB toolboxes can be used together to handle a real-life engineering...

This function generates a Timeseries file which can be used for Moore FSM coverage analysis.The file is generated in the working directory and can be opened into the Workspace for use by MATLAB, or read directly into Simulink using the 'Import Data From File' source block.The generated Timeseries...
