 ## Run MATLAB Command
-When you define your workflow in the `.github/workflows` directory of your repository, specify the **Run MATLAB Command** action as `matlab-actions/run-command@v1`. The action requires an input.
+When you define your workflow in the `.github/workflows` directory of your repository, specify the **Run MATLAB Command** action as `matlab-actions/run-command@v1`. The action requires an input and accepts an optional input.
 
 Input                     | Description
 ------------------------- | ---------------
-`command`                 | (Required) Script, function, or statement to execute. If the value of `command` is the name of a MATLAB script or function, do not specify the file extension. If you specify more than one script, function, or statement, use a comma or semicolon to separate them.<br/>**Example:** `myscript`<br/>**Example:** `results = runtests, assertSuccess(results);`
-
-MATLAB exits with exit code 0 if the specified script, function, or statement executes successfully without error. Otherwise, MATLAB terminates with a nonzero exit code, which causes the build to fail. To fail the build in certain conditions, use the [`assert`](https://www.mathworks.com/help/matlab/ref/assert.html) or [`error`](https://www.mathworks.com/help/matlab/ref/error.html) functions.

For more information about startup options, see [Commonly Used Startup Options](https://www.mathworks.com/help/matlab/matlab_env/commonly-used-startup-options.html).<br/>Using this input to specify the `-batch` or `-r` options is not supported.<br/>**Example:** `startup-options: -nojvm`<br/>**Example:** `startup-options: -nojvm -logfile mylogfile.log`
 
 When you use this action, all of the required files must be on the MATLAB search path. If your script or function is not in the root of your repository, you can use the [`addpath`](https://www.mathworks.com/help/matlab/ref/addpath.html), [`cd`](https://www.mathworks.com/help/matlab/ref/cd.html), or [`run`](https://www.mathworks.com/help/matlab/ref/run.html) functions to put it on the path. For example, to run `myscript.m` in a folder `myfolder` located in the root of the repository, you can specify `command` like this:
