Hi Akhshay,

It is my understanding that you are facing issues while using the “stlwrite” function. The issue is caused by the incorrect placement of the passed parameters in the calling syntax for the "stlwrite" function.

Refer to the examples listed in the following documentation of “stlwrite” function to learn how to use “stlwrite” function correctly- https://in.mathworks.com/help/matlab/ref/stlwrite.html

Hope this helps in fixing the “stlwrite” error.

Regards,

Vinayak Luha
