Regarding this question:
Find the attached sample model (‘trial_model.mdl’)where there are multiple ‘Gain’ blocks in the top model and also in subsystem. The path and names of all the ‘Gain’ blocks present in the model ‘trial_model’ can be found by the following command:
>>block_name = find_system('trial_model', 'BlockType', 'Gain')
Here block_name will be an n*1 cell array containing the names of all the ‘Gain’ blocks present in the model ‘trial_model.mdl’.
Then you can consider to run the following loop to change the parameters of each of the block. You can refer to the following sample code:
>> n=length(block_name)
for i=1:1:n
set_param(block_name{i,1},'Gain','15') %%Changing ‘Gain’ of all the ‘Gain’ blocks to 15
end
