Sine Wave not recognize with find_system

I am finding the path for Sine Wave block so that can replace a block in f14 model. However, when I use

find_system(simulinkModel, 'BlockType', 'Sine Wave')

The output said it empty and cannot find it

0×1 empty cell array

But if I replace Sine Wave with Step block it said

1×1 cell array
    {'simulink/Sources/Step'}

Am I mistake something or SIne Wave cannot be found when using find_system

Answer 1

The 'BlockType' for the "Sine Wave" is 'Sin'.

Answer 2

You are right. Its name contains two words and because of that, supposedly it fails to locate it.

is there any chance to fix this problem?

[Sulaymon Eshkabilov]

The solution to your exercise is to rname the block that can solve this issue. How to rename the block, see the link: https://www.mathworks.com/matlabcentral/answers/275089-rename-or-reorganize-simulink-library-blocks#:~:text=e.g.%20right%20click%20on%20the,Simulink%20models%20are%20renamed%2Fupdated.

The solution for this maybe too complicated, but it can only barley accepted from some perspectives. But thanks

Good luck.
