Bus elements with multiple dimensions

I have a structure S with three time series fields a, b and a.

S.a = timeseries
S.b = timeseries
S.c = timeseries

I'd like to create a bus object (B) with above bus element. But instead of creating 3 bus elements (a, b and c) I'd like to create one bus element (S) with dimension of 3. I created the bus B like this:

S            = Simulink.BusElement;
S.Name       = 'S';
S.Dimensions = 3;

B          = Simulink.Bus;
B.Elements = S;

How can I assing (sub)bus elements (a, b and c) to S (and B)?

Hi Alborz,

To create a Bus Object “B” that contains a single Bus Element “S” which itself represents a structure with three timeseries fields “a”, “b” and “c”, you will need to create a nested bus structure. This involves creating Bus Objects for both the outer structure “B” and the inner structure “S”, and then defining “a”, “b”, and “c” as elements within a bus that “S” represents. Here is how you can do it on MATLAB R2020a:

• Define Bus Objects for “a”, “b”, and “c”.

elemA = Simulink.BusElement; 
elemA.Name = 'a'; 
elemB = Simulink.BusElement; 
elemB.Name = 'b'; 
elemC = Simulink.BusElement; 
elemC.Name = 'c'; 

• Create a Bus Object for the inner structure “S”.

S = Simulink.Bus; 
S.Elements = [elemA elemB elemC]; 

• Create the outer Bus Object “B” and add “S” as a datatype.

elemS = Simulink.BusElement; 
elemS.Name = 'S'; 
elemS.Dimensions = 1; 
elemS.DataType = 'Bus: S';  
B = Simulink.Bus; 
B.Elements = elemS;
