changing parameters in locked library (simulink)

[Bernt]

Hi everybody,

I am trying to change the parameters of a block within a locked
library using the 'set_param' command. I don't want to unlock the
library manually by using 'Edit->Unlock library' but rather from
within the source code. I read somewhere that I should break the links
(e.g. set_param('<library>/<block>','LinkStatus','none'); ) but
unfortunately this uses 'set_param' as well and I still get an
Error-Message saying that I attempt to modify a locked (read-only)
library.
What am I doing wrong or is there any other way to solve this problem?
Thanks for any help,

Bernt

Hi Bernt,

Better ways to solve this might be:

1) Create your own custom library containing the original block (with the
original library link removed - just make it your own library block now with
the parameters you want set the way you want before saving your new
library).

2) Use the original library block in a model and do appropriate set_param
commands on the block(s) only in model(s). There would be no issues with
library unlocking then... ;-)

hth,
Steve

Thanks a lot, even though I might be a little late (but I only work
once a week). I even figured it (choice 2)) out before I read your
post
but it's nice to know where to find people that are willing (and of
course able) to help :-))

Hi Bernt

I am facing the same kind of Problem, since I intend to change the MaskPrompts based on a chosen Popup-Option (in the same mask). This works fine with set_param, but when I add my block to my library and use it I get the same error as you.

Do you mind telling me how I can address just the block in the current model and not the block in the library. I tried the full path of the block ('model/block'), as well as gcb and gcbh and none of it worked.

I doubt it is necessary to rebuild the whole mask as GUI, but it is the only way I can think of to fix this issue.

Your help would be greatly appreciated.

Thanks
