set_param() - programmatically change param of multiple blocks of the same type (for-loop)

5 vues (au cours des 30 derniers jours)
Hi everyone!
Suppose there are 50 blocks of the same type in a simulink/simscape model - let's say it is a pipe-block in simscape domain.
Is there any recipe to change a specific parameter of all blocks programmatically?
I have a solution, but it assumes that the bocks of the same type are named with a consecutive number like this: pipe_1, pipe_2.
for iter_pipes = 1:50
set_param(...
model_name + "/pipe_" + string(iter_pipes),...
"p_I_specify","on",...
"p_I_priority","High",...
"p_I","550000"...
)
end
Is there any way to access a specific param of multiple blocks of the same type regardless of the blocks name?
Thank you in advance for any help!
Michael

That´s a good solution. For any other case, you might try to first use the command find_system, to then look for the blocks you want to change.
The following link has some examples of how to use this command:

Thx Jeúsus for the quick response.
Got a second solution, which takes a str. for searchin' specific blocks.
In my case it is more appropriate solution, cause i have to handle with pipenames like pipe_12_a, pipe_12_b....
model_name = "SIM_X";
all_simscape_blocks = find_system(model_name);
simscape_blocks_pipes_idx = startsWith(all_simscape_blocks,"SIM_X/pipe");
simscape_blocks_pipes = all_simscape_blocks(simscape_blocks_pipes_idx);
for i = 1:length(simscape_blocks_pipes)
set_param(...
simscape_blocks_pipes(i),...
"p_I_specify","on",...
"p_I_priority","High",...
"p_I","550000"...
)
end
