Hi Rajeev,
To clarify - there are two ways I can interpret your question primarily because 'exporting' a SimBiology model can mean two things:
  1. You can export the SimBiology model from the SimBiology Desktop to the MATLAB Workspace, by right clicking on the model and selecting "Export to Model to Workspace..."
  2. You can export a SimBiology model by calling the function 'export' on a SimBiology model. This exports the model for standalone and deployment applications.
If you meant the first form of exporting, and assuming your SimBiology model is now in your MATLAB workspace in a variable called m1, you can access the parameters as follows:
>> params = sbioselect(m1,'Type','parameter');
This will yield a SimBiology Parameter array:
SimBiology Parameter Array
Index: Name: Value: ValueUnits:
1 ka_Central 1 1/hour
2 Cl_Central 1 liter/hour
3 ke_Central 1 1/hour
4 absorption rate 1 milligram/hour
Say you now want to change the Value of ke_Central to 2, you can use the following command:
>> params(4).Value = 2;
If and only if all your parameters are model scoped, you can also access the parameters using
>> modelscopedparameters = m1.Parameters;
If you meant the second scenario, things are a bit more complicated and there is no easy way to change parameter values. As an alternative to the 'exported SimBiology object', you could consider using a SimFunction.
Let me know if that helps.

Thanks Sietse for providing the relevant solution. I guess simfunction and your suggestion may work for me. I will let you know after the implementation.
Best Regards,
