MATLAB: Changing StartTime of Protected Model

protected modelsimulinksimulink codersolverstart timestarttime

Hi,

I'm trying to edit the simulation start time (for the solver) of a protected model. I tried setting the value of the start time as a tunable variable but that didn't work.

Can I actually edit the start time after I creat the protected model? if yes, how?

Thanks

The Simulink software stores the protected model as a compiled MEX binary. Hence it is not possible to change any solver configuration once you generate a protected model. This is by design and an expected behavior of protected models.

MATLAB: Can the code-generation parameters of a protected model be changed after protection

Hi Casey,

It is not possible to alter a model once it has been protected since that would defeat the purpose of protecting it. This includes code-generation configuration parameters.

In R2015a, it is possible to include multiple targets in a protected model. Each target is identified by its System Target File. Thus you could potentially have two targets, each configured differently, inside the same protected model. This might help solve your issue.

MATLAB: Protected External Methods

http://www.mathworks.com/help/techdoc/matlab_oop/brqy3km-14.html#brqy3km-15 under "Specify Method Attributes in classdef File" ...

Basically, inside the class definition create a methods block with properties Acess = protected. Inside that block add the function footprint.

methods (Access = protected)
  [a,b,c]=protectedmethod(x,y,z);
end

Then create a seperate m file in the root class directory named protectedmethod with the header

function [d,e,f]=protectedmethod(u,v,w)
