Hi,

I am using R2007b.

I have a masked subsystem ('NonLinModel/NonLin') that contains a block ('NonLinModel/NonLin/AdaptiveParam') that I'd like to duplicate within the initialization callback script. When I execute the add_block() function as per the documentation,

add_block('NonLinModel/NonLin/AdaptiveParam', ...
'NonLinModel/NonLin/AdaptiveParam2');

I fail with an exception

MException object with properties:

identifier: 'Simulink:SL_AddBlockInvSrcBlock'
message: 'Invalid source block specification.'
stack: [2x1 struct]
cause: {}

Why? add_block() seems to indicate that I can do this.

Thanks.

You seem to be doing the right thing.

There was a time when for a mask to modify the underlying block you needed to set the masked subsystem's MaskSelfModifiable property, i.e.
>> set_param('NonLinModel/NonLin','MaskSelfModifiable','on');

But in more recent releases that's only required if the masked subsytem is part of a library.
I don't remember when that change came about, but you might try it and see if it works for you in R2007b.

Hi Phil,

Thanks for the tip, even though it doesn't have any effect. Setting that property gives me the Invalid source block exception. But I can get the property and it is 'on'.

I searched the newsgroup and found a similar question. Someone suggested writing an s-function to encapsulate the variability, so I've done that. Unsatisfying not to have an answer, but I can live with it.

I can put my components into a library and it will work. That just means my library contains a "do not use this" component block.

Thanks again for your help.

-John.
