I have a simulink model where on the first iteration i want to open up an actxsever for excel Then on other iterations i want to 'iterate' on it, by writing to it each iteration, but the problem is, i cant seem to have one matlab function block call it, and another one iterate on it.

In other words, when i do the following... Excel = actxserver('Excel.Applicatoin'); Workbook = Excel.Workbooks.Open(filename); in an MATLAB function block in simulink. I cannot save Excel or Workbook variables to be called elsewhere in the model...

Ive tried DataStore, but it doesnt seem to allow that datatype...

Is there a way to store the variable Excel = actxserver('Excel.Application'); in a block to be used at other points in the model?

Thanks
