munlock(fun)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
name | StringScalar | No | — | Function, script, file, command, or option text. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:TooManyInputs | A debugger compatibility helper receives more inputs than it supports. | debugger helper: too many input arguments |
RunMat:InvalidInput | An input is not a supported text, scalar, or option value. | debugger helper: invalid input |
RunMat:NoCurrentFile | `mlock`, `munlock`, or `mislocked` is called without a current function or script. | debugger helper: no current function or script is available |
RunMat:FileNotFound | `dbtype` cannot resolve a MATLAB source file. | dbtype: file not found |
RunMat:FileReadFailed | `dbtype` cannot read the resolved source file. | dbtype: failed to read file |
How munlock works
munlockwith no input unlocks the active function or script.munlock(fun)unlocks the named function or script.- Unlocking an unlocked name is allowed and has no effect.
Does RunMat run munlock on the GPU?
munlock is host-side execution-state bookkeeping and has no GPU/provider behavior.
Example
Unlock a named function
munlock('myFunction')Using munlock with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how munlock changes the result.
Run a small munlock example, explain the result, then change one input and compare the output.
