Building Simulink Modell from Matlab Code

Hi there,

I am currently trying to build Simulink models from Matlab code and have some problems with.

My main problem is to figure out the names and/or path' of the blocks and their parameters. To find the block names I could find a workaround but I have no clue how to figure out the proper names of the parameters of one block. I would very appreciate if someone could tell me a function that returns the parameters or some workaround, so that I can change the parameters with

set_param('path to block','parameter name','parameter value')

Thank you very much!

Regards,

I should probably be more precise: When talking about parameters I mean the parameters that are shown in the GUI when double clicking a Simulink block.

This is not clear

Can you explain with an example?

get_param('path to block','DialogParameters')

Perfect! Thank you so much. Now I wonder why I didn't figure that out myself :/

Thank you so much! Any chance you have a good way to figure out the modules paths as well?

My current work around is as follows:

open_sysmte('simulink') navigate to the according block after clicking the block 'gcb' returns the according path.

is their a more simple way to get the path to a block?

The question is: to get the path from what? What is your input?

[Lennart]

There sure will be no function that I can give an input. I want to add blocks to my model using add_block(...), but when I brows through the library browser I can't find the path that the add_block - function requires.

For example I want to add an input port. I can find that in the library browser under Simulink -> Ports & Subsystems -> In1. When I want to add it using add_block. I will have to enter the path 'built-in/Inport'. The question is, how can I figure out that path, since I can't find it in the library browser.

I am not following you, each block is located somewhere in Simulink librairie

[Lennart]

I don't know how else I should explain it. Just take the example. The path that you click with the mouse has nothing in common with the path that needs to be entered in the add_block-function. Of course every block is located somewhere in the Simulink library but how am I supposed to figure out where if the path that I take in the Simulink library browser is not what I have to enter in the add_block-function.

This for example is how I use the add_block-function to add an input port:

add_block('built-in/Inport',[opt.sys '/Signal' num2str(i)],'Position', pos);

Guess I will stick to my workaround then. Thank you for time and help!!!

If you have a liste of blocks that a user can choose. You can associate to each block a path. Just create another liste of path
