Today I would like to ask you a question.<\/p>\r\n\r\n

This week I received a large model where I wanted to find all the Lookup Table<\/a> blocks and modify their Index Search Method<\/tt> parameter. Since the model was quite large and I was not familiar with it, manually navigating to each block, opening its dialog and modifying it was not an option.<\/p>\r\n\r\n

So my question is: How would you accomplish this task?<\/em><\/p>\r\n\r\n

Here are two options I considered.<\/p>\r\n\r\n

Using functions at the MATLAB command prompt<\/strong><\/p>\r\n\r\n

For a long time, when I needed to find or modify blocks in a large Simulink model, I used the command prompt and functions like find_system<\/a><\/tt>, hilite_system<\/a><\/tt> and set_param<\/a><\/tt>.<\/p>\r\n\r\n

For the example described above, I can find the blocks using find_system<\/a><\/tt> and see how they are connected in the model using hilite_system<\/a><\/tt>:<\/p>\r\n\r\n

\"Finding<\/p>\r\n\r\n

To change the Index Search Method<\/tt>, I can use set_param<\/a><\/tt> on the previous results:<\/p>\r\n\r\n

\"Configuring<\/p>\r\n\r\n

Using the Model Explorer<\/strong><\/p>\r\n\r\n

Recently, I started using the Model Explorer<\/a> for this type of task and I think it is very efficient.<\/p>\r\n\r\n

For the same task as above, I can easily search by block type. One thing I like is that I do not need to remember the exact string for the block type. The drop down looks at my model and offers me a list based on the blocks in my model.<\/p>\r\n\r\n

\"Finding<\/p>\r\n\r\n

In the list of results, the Path column is a hyperlink I can click to immediately see where the block is in the model.<\/p>\r\n\r\n

To edit the Index Search Method<\/tt> for all the blocks found, I:\r\n
