Why can't find_system find IC block?

I would like to find all initial condition blocks in my Simulink model, yet the following returns an empty cell array,

thisBlock = find_system(bdroot, 'BlockType', 'IC')

Can you correct this call to find_system? When I click on the block, gcb returns 'myModel/IC', so I believe the block type is correct.

The IC block's BlockType is 'InitialCondition', so you should be using find_system(bdroot, 'BlockType', 'InitialCondition'). I would recommend using find_system(bdroot, 'LookUnderMasks', 'on', 'BlockType', 'InitialCondition') if you want to search inside masked subsystems also.

Thanks as always! I had thought the block name (IC) was the same as block type (IntialCondition), so good to know that they are not. In case it is helpful to someone:

1) To find the block type,

get_param(gcb,'BlockType')

2) To highlight all such blocks,

thisBlock = find_system(bdroot, 'LookUnderMasks', 'on', 'BlockType', 'InitialCondition') ;

hilite_system(thisBlock, 'find') ; % Turn highlighting on

hilite_system(thisBlock, 'none') ; % Turn highlighting off
