MATLAB isn’t intended to be an engineering design graphics language, but there is a possible way to do what you want. I have very little experience with this, and no experience remotely similar to what you want to do, so unlike your previous Questions, I’ll be of very limited help.
One possible method is to Create Object Groups from your gear tooth, then use hggroup, makehgtform, and hgtransform to position (translate) it and rotate it. You will have to do this around the entire circumference of your gear, so you will have to choose where to place it and how much to rotate it.
You can translate it using essentially the same sin and cos calls I used to draw the circles in my previous code. You might consider tan to do the rotations, but that is simply a suggestion.
Once you get the code for this working, submit it to the File Exchange with appropriate documentation. I was not able to find anything remotely similar. If you have access to SimMechanics (a Simulink Toolbox), see if it has anything about specifying, designing, and drawing gears.
Good luck!
