In the era of , axescheck has become even more relevant. When building apps, you almost always want to point your plotting functions to a specific UIAxes component within the app UI rather than letting them "pop out" into a new figure window. Including axescheck in your internal library functions makes them "App-ready" by default. Conclusion axescheck

: Manually checking isa(varargin{1}, 'matlab.graphics.axis.Axes') is tedious and error-prone, especially when dealing with empty inputs or different types of containers. : If the first argument is not an axes handle (e

plot(ax, y) — Plots specifically in the axes defined by the handle ax .

If you are writing a custom plotting utility, using axescheck ensures your function feels like a native part of the MATLAB ecosystem.
