What is ROC in Z-transform?
Region of convergence. The region of convergence (ROC) is the set of points in the complex plane for which the Z-transform summation converges.
How do you represent Z-transform in Matlab?
ztrans( f ) finds the Z-Transform of f . By default, the independent variable is n and the transformation variable is z . If f does not contain n , ztrans uses symvar . ztrans( f , transVar ) uses the transformation variable transVar instead of z .
How to find ROC in Matlab?
You can calculate ROC curves in MATLAB® using the perfcurve function from Statistics and Machine Learning Toolbox™. Additionally, the Classification Learner app generates ROC curves to help you assess model performance.
