Dear all,

I have a simple Simulik model seen below:

a,b,c are defined as follows:Simulink.parameter,Double,ExportedGlobal ,Tunable and have intitial values of 1 , 2 , 3 respectively.

I highlight the tf1 block and write in the command window:"set_param(gcb,'Realization','general')"

Then,I write "[parm_struct]=rsimgetrtp('model')" hoping to get a structure containing the model parameters :a,b,c.But I can see only the values 1,2,3.

If the model has 20 transfer functions,I will get a long vector of values,and I will spend some time to decide which value belongs to which parameter of which transfer fun.

My question is how to find a way to access names instead of local addressable values in the param_struct output.

Thanks for the reply in advance,

M.E

Hi,

I am new beginner for simulink. When I run something like "parm_struct =rsimgetrtp('my_model')", I always got the following error. Do you have any idea on how to solve this problem?

'rsimgetrtp' requires one of the following:

Embedded Coder

Simulink Coder

Thanks in advance!
