: Start with the function keyword, define outputs, and ensure the filename matches the function name. Example :
: After writing several feature functions, you can use algorithms like Sequential Feature Selection to identify which ones are most predictive. matlab-2017
function featureValue = getMeanAmplitude(signal) % This function calculates a simple statistical feature featureValue = mean(abs(signal)); end Use code with caution. Copied to clipboard 2. Feature Engineering Workflow : Start with the function keyword, define outputs,
: You can use functions like gencfeatures to perform automated feature engineering if your data is in a table. : Start with the function keyword
Introduction to Feature Selection - MATLAB & Simulink - MathWorks
In MATLAB, features are usually calculated within functions that take raw data as input and return a single value or vector.
