Is there any way to access the text of a Simulink DocBlock ?

Does anybody know a way to access the Text of a Simulink DocBlock in a model via command line, using find_system command ?

Answer 1

[TAB]

% Find docblocks in model
dBlkH = find_system('MyModel', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock');

% Extract the docblock text
dBlkUData = get_param(dBlkH(1), 'UserData');
bBlkText = dBlkUData.content;

Thanks Tabrez, this is helpful ! :-)

If I add a 'FindAll', 'on' it is returning me the Handles to the DocBlocks (otherwise a cell array). I can use either of it.

>> dBlkH = find_system('tl_vwe_model', 'FindAll', 'on', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock')

dBlkH =

    5.0002
    8.0002

>> dBlkH = find_system('tl_vwe_model', 'BlockType', 'SubSystem', 'Mask', 'on', 'MaskType', 'DocBlock')

dBlkH =

2×1 cell array

    'tl_vwe_model/ChangeHistory'
    'tl_vwe_model/Requirements'

I still do not know why this only finds the blocks on top model level (not in the lower subsystem levels).

[TAB]

Above search command should find the DocBlock in all level of model.

Try to use the 'SearchDepth' option and check there is any difference.

尝试引用非结构体数组的字段。

bBlkText = dBlkUData.content;
