Loading Structure from base workspace to embedded matlab
2 views (last 30 days)
Does anyone know how to load a structure from base workspace to embedded matlab ?
The structure itself is a combination of constants and sub-structures containing more constants and all I really want is all this information to be made available in the embedded matlab function scope.

You need to define the scope of the structure as a parameter, not an input (which is the default). Here's a simple example. In the base workspace, I have defined:
s = struct;
s.a = 1;
s.b = 2;
and then I have a MATLAB Function block (previously called Embedded MATLAB Function):
function y = fcn(u,s)
y = s.a * u + s.b;
and s is defined as a parameter in the Model Explorer and it works fine. See Working with Structures and Bus Signals in the documentation.

From the documentation, "The Embedded MATLAB Function block accepts inputs of any type that Simulink supports, including fixed-point and enumerated types. For more information, see Data Types Supported by Simulink in the Simulink documentation."
Looking further, structure data is not supported by Simulink. I guess you have to flatten your structure data then.
