In MATLAB, features are usually calculated within functions that take raw data as input and return a single value or vector.
: After writing several feature functions, you can use algorithms like Sequential Feature Selection to identify which ones are most predictive. matlab-2017
: The Diagnostic Feature Designer (available via the Predictive Maintenance Toolbox ) allows you to interactively extract features and then generate MATLAB code to automate the process for future data. 3. Writing Features to Files In MATLAB, features are usually calculated within functions
