The variable browser is only updated when matlab returns to the command line. Otherwise the cost of updating the browser could be very high.

Hi,
I understand that you have noticed a difference in the behavior of the workspace when running code versus debugging.
In MATLAB, variable may not appear in the workspace during code execution but can be visible during debugging due to various factors:
- Execution flow: When code runs without debugging, MATLAB executes it sequentially, potentially resulting in quick completion or variable clearance, leading to no variable display.
- Scoping: MATLAB has different scoping rules for variables. Variables defined within functions have local scope. Variables defined in the command window or scripts have global scope.
- Breakpoints: Debugging with breakpoints enables pausing code execution at specific lines, facilitating variable inspection.
Please refer to the following documentation for more information.
I hope it helps!
Thanks.
