pass matrix to EML in stateflow...

I have defined an data store memory to share with a stateflow chart. The size is defined as [10 5]. In the stateflow chart, I need to pass the contents of the data store memory to an embedded matlab function (newlist = addToList(dsmlist)).

When I compile the chart, i receive an error

----- Index expression out of bounds. Attempted to access element 2. The valid range is 1-1. More information

Function 'addToList' (#66.95.96), line 6, column 18:"2" Launch diagnostic report. -----

I cannot figure out how to tell the compiler the size of "dsmlist" so that it will continue compiling.

The error seems to be coming from Function 'addToList', line 6, column 18 can you post the corresponding code at that line?
