Executable build with Matlab Application Compiler returns error: Undefined variable "Simulink" or class "Simulink.Parameter"

Hello together,

I'm building a Standalone Application with the Matlab Application Compiler based on matlab scripts. In one matlab script a parameter is set as a Simunlink.Parameter object like this:

function SetSimulinkParameter(name, value)

tmp = Simulink.Parameter;

if isnumeric (value)

tmp.Value = value;

tmp.DataType = 'double';

tmp.DocUnits = '';

tmp.Description = '';

tmp.Min = -1e10;

tmp.Max = 1e10;

tmp.CoderInfo.StorageClass = 'Model default';

assignin('base',name,tmp);

end

When running the Standalone application, the following error pops up: Undefined variable "Simulink" or class "Simulink.Parameter". The error points to the second line:

tmp = Simulink.Parameter;

When running the matlab script in Matlab, the scripts works fine.

How can I build a Standalone Application, that sets and reads Simulink.Parameter objects?

Hi,

I am facing the same issue. Were you able to resolve it?

Hi,

no. not yet.

Best regards

We think, that this error appears, because the Matlab compiler cannot compile Simulink functions. Therefore the Simulink compiler is needed.

However the Matlab Application Compiler uses the mcc - Matlab compiler and not the Simulink Compiler. We will replace the Simulink.Parameter object by a struct.
