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

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

isdeployed

Expected 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.

Open-source implementation

Unlike proprietary runtimes, every RunMat function is open-source. Read exactly how isdeployed is executed, line by line, in Rust.
