I want to generate sine wave in Simulink by using the MATLAB function. I could not get the actual sinewave. And could not find the problem also, Please see the picture attached below to get a clear picture of my problem. And the code I used for MATLAB function works fine in MATLAB.

You could just use the sine wave block ?

If you really want to use a matlab function, you need to do :

here, the Matlab function generates the exact same sine as the sine wave block.

I actually need to generate waveform like this,

They are basically all positive half cycles of full sine period. And after each half a there will be zero intervals as shown in the figure above. I need to generate this kind of waveform in simulink. Could you please suggest me how to do so? It seems with MATLAB function I won't be able to do such because of the fixed clock. Thanks in advance.

Kind Regards
