How does this work?
1.ssThe Dataset is created from a models interface (root inports).
2.ssThis Dataset is then populated with data specified by you. If your data is of the wrong type, data will be cast to the datatype of the root inport.
3.ssIf placing this Dataset in the base workspace, you can set up this Dataset as external inputs to the model and simulate.
a.ssUse Configuration Parameters to set external input string, or
b.ssUse Root Inport Mapping with port order or block name mapping mode.
What is supported?
1.ssBuilt-in datatypes
2.ssEnumerations
3.ssSignals with dimensions (scalar and array)
What are the limitations?
1.ssNo busses
2.ssNo array of busses
3.ssNo functions calls
See tryMe*.m in the project for examples of how to use in a MATLAB script.
