The template includes an s-function (sfun_cstr_apm.m), SIMULINK model (cstr_simulink.mdl), cellwrite.m (also available on Matlab Central), and several APMonitor files for a CSTR example.
The operating instructions for this interface is provided in the s-function header comments. The only additional file needed to run this example successfully is the apm.exe file - this may be obtained from the APMonitor website.
Ben created some impressive Fuel Cell simulation results from the development of this interface. He posted some information to the APMonitor web-site here:
