Getting the following error in Simulink: "Global declaration not resolved to a Data Store Memory block registered via the Ports and Data Manager."
Background: I am trying to run simple code inside a Matlab function block and require a variable GEAR initialized to 1 only at the beginning of the simulation so the Function Block code can increment/decrement GEAR. I have tried declaring the variable as "global GEAR" and then "GEAR = 1" in Callbacks - InitFcn, as well as placing in a .mat file but but get the error above when the variable GEAR is used within the Matlab Function Block.
I have not been successful (even with Matlap documentation) to use the Data Store. And more to the point think there must be an easier way to do such a basic thing as initialize a global variable than start creating data stores. And what/where is the "Ports and Data Manager" - it doesn't even come up in the help file seach.
Any help appreciated.
