MATLAB: Sine Wave not recognize with find_system

Question

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'.
