unrecognized method, property, or field "cla" for class "matlab.ui​.control.U​IAxes".

Hi, I got this error in the matlab when running a program. It causes problems in the running the program itself later. Can I know what it means by "unrecognized method, property, or field 'cla' for class 'matlab.ui.control.UIAxes' " ? How can I fix it ?

Thanks a lot!

Not sure if this is a graceful solution. We have a MATLAB code, with the GUI made using App Designer that gave the same error

Unrecognized method, property, or field 'cla' for class 'matlab.ui.control.UIAxes'.in R2020b. Suspect there is a difference in how R2020a vs. R202b clears current axes. Re-opening the same MATLAB code, without any changes, in R2020a solved the issue for us

Hi Eden,

I am assuming that you are using “cla” as a method or property of UIAxes.

The intended use of “cla” is as a function.

cla(axes) 

You can refer to the documentation below

Clear axes - MATLAB cla (mathworks.com)

Thanks a lot for the information! It is good to know that!

It is the Matlab version problem, too new to run the app.

Hey. Did you find a solution?

Maybe he tried to do something like

axesHandle.cla % cla is not a method or property of the axes handle.

instead of

cla(axesHandle);
