getcallinfo — Return deterministic information about the current RunMat call context.
getcallinfo is an undocumented MATLAB-adjacent compatibility helper. RunMat exposes deterministic call-context metadata for client code that probes it.
Syntax
info = getcallinfoReturns
| Name | Type | Description |
|---|---|---|
info | Any | Scalar struct describing the current call context and stack. |
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 getcallinfo works
getcallinfoaccepts no inputs.- The result is a scalar struct with
name,file,line, andstackfields. stackuses the same 1-by-N cell row of frame structs asdbstack.
Does RunMat run getcallinfo on the GPU?
getcallinfo is host-side call-context introspection and has no GPU/provider behavior.
Example
Read the current call context
info = getcallinfo;Using getcallinfo with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how getcallinfo changes the result.
Run a small getcallinfo example, explain the result, then change one input and compare the output.
FAQ
Is getcallinfo full MATLAB API compatibility?⌄
No public MathWorks API contract was used for this helper. RunMat provides stable current-frame and stack metadata for compatibility with code that checks for its existence.
