[Simulink] How to find different Sample Time blocks

Hello

I am 2012b version user.

on simulink my model, There are two different sample time legens as below (checked using Display- Sample Time - All menu)

(Ammotation - Description - value

    D1      - Discrete1   - 0.03 
   inf      - Constant    - inf)

My Model is set for discrete simulation. I'd like to find inf constant blocks to make it discrete. However, I checked almost block's sample time setteing manually, but I couldn't find the block which has inf configuration. (All annotation of arrows shows D1- Discrete message)

so, I want to know how to find the block which has the different sample time automatically or manually

Thank you in advance.

Hi,

I guess you'd like something like

% get all constant block in the model
AllConstBlocks = find_system(bdroot,'BlockType','Constant');

% loop on all these block
for i = 1:length(AllConstBlocks)
    % if the sample time is inf, then display the full path to the block
    if strcmp(get_param(AllConstBlocks{i},'SampleTime'),'inf')
        disp(AllConstBlocks{i});
    end
end

you can adapt this for different kind of block, or other sample times.
