How to access a signal from a bus structure inside matlab function

Is it possible to select a signal from a bus structure inside a MATLAB function and then scale it and then assign it to an output?

e.g. some thing like the following:

function [output] = myfunc(input, signalSelection, scaling)
% #codegen

output = input(signalSelection)*scaling;
end

where input is a defined bus structure, signalSelection is a uint32 and scaling is a single?

The error I keep getting is "Function 'mtimes' is not defined for values of class 'struct'."

I understand that you want to access a single signal from a Bus structure in the MATLAB workspace.

Assuming that you are using "Simulink.Bus.createMATLABStruct" to create the Bus structure "input" mentioned in your code snippet, you can access its fields with a dot operator and scale it using the "scaling" parameter. For example, if your Bus structure has a signal "pulseSignal", you can access it as

 >> output = input.pulseSignal * scaling

Hope this helps!
