What does catch() do?
Error handling. Executes the try block. If an error occurs, execution jumps to the catch block where the error message is available in the catch variable. See also: help try. It is a MATLAB®-compatible programming function available in SimLab with the same calling syntax as MATLAB® — typically: try ... catch e ... end.
Can I run catch() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls catch(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
