I want to suppress: useCS = logical 1 in command window

This "spam" repeats over and over in the command window. I want to suppress this.

useCS =

logical

1

useCS =

logical

1

In debug mode (output) I got this:

I tried several solutions suggested by grok/chatGPT but none of them worked. Im using R2026a so it might be a internal bug.

useCS = logical 1 Attempt to modify the tree during an update traversal. Error in matlab.graphics.interaction.internal.UnifiedAxesInteractions.setDefaultBehaviorForText

Without knowing more about your code or what it is dooing, see if puttting a semicolon (;) at the end of the line that assigns 'useCS' solves the problem.

(There is not enough information provided to suggest any other solution.)

Since you are using the R2026a pre-release, you need to contact the appropriate support at MathWorks. This may be a bug they need to know about.

Also, if you have access to R2025b, see if it produces the same error.

You can tell MATLAB to enter debug mode when unsuppressed output occurs. Use this to determine where the semicolon on the line that assigns to the useCS is located, then add the semicolon.
