Hi Bryan,
The model passed to your custom task is not decided by what models are in the MATLAB workspace. It is a configurable item that can be configured from the MODEL section of the TASK tab. Functions that print(e.g. disp) to the command line are currently ignored when the custom task is being executed.
There are two return variables from the task: data and taskInfo. After the task has successfully executed both these variables are exported to the MATLAB workspace and can be examined there. Note that the variable "data" from the task comes in as "tobj". Exporting of data to workspace is controlled by a preference that can be accessed from the HOME tab by clicking on "settings".
