isdeployed — Return false because RunMat is not MATLAB Compiler deployed code.
isdeployed returns a logical scalar indicating whether code is running as a MATLAB Compiler deployed application. RunMat always returns false.
Syntax
value = runtimeCompat(args...)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
args | Any | Variadic | — | Version query arguments. |
Returns
| Name | Type | Description |
|---|---|---|
value | Any | Version or logical result. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:runtimeCompat:InvalidInput | Arguments are malformed or unsupported. | runtime compatibility helper: invalid input |
How isdeployed works
- The builtin accepts no input arguments.
- The result is always false in RunMat.
Does RunMat run isdeployed on the GPU?
No GPU kernels are launched.
GPU memory and residency
The result is a host logical scalar.
Example
Checking deployment status
isdeployedExpected output:
ans = logical(0)Using isdeployed with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how isdeployed changes the result.
Run a small isdeployed example, explain the result, then change one input and compare the output.
FAQ
Can RunMat run MATLAB Compiler deployed code?⌄
No. This predicate exists so compatibility branches can execute deterministically.
