I have a simulink model with a Matlab Level-1 S-Function block. It has some parameters that are all written in structure form and constant valuse. I want to vary one of these valuse in a specific range , sth like "for loop" , and to have the certain and seperate output values for each of those variable values. how can I do this ? Also can we use an S-Function in a for loop ? for example by handling or inlining it ? Details are here: First I wrote an M-File and defined my parameters : v_data=struct('Kcr_f',1,'Kcr_r',1,'u0',30)
then I developed my S-Function ,specified v-data in "mdlInitializeSizes" ,and run it very well; Yes , no problem with these constant valuse.
Now I want to vary the parameter "u0" from 1 to 40 and have seperate outputs from each of these varying values ; how can I do this ?
Tnx for your attention

the parameters which has to be varied should be declared as parameters in the function definition of the s function.
