Details:

Maybe I overlook something, but:

sombrero
get (gca, "cameraposition")
ans =

   -91.3142  -119.0030     6.3622

>> set (gca, "cameraposition", [-910, -420, -20])
>> drawnow
>>


doesn't update (rotate) the plot.
Only after I press the "rotate" button and click in the figure, the figure
suddenly rotates to the new camera position property.

=> Shouldn't it rotate immediately after the set() command, or after
"drawnow"?

Matlab (r2015a) does rotate a 3D plot (= adapts to new cameraposition)
immediately after the "set" command.

After the above actions, trying to rotate the plot by dragging with the mouse
doesn't work anymore. Apparently the "camerapositionmode" remains fixed to
"manual". 
That seems aother ML incompatibility; ML resets the camerapositionmode to
"auto" after clicking the "rotate" button and dragging a 3D figure corner. To
be honest, I'd expect user actions like clicking a button to override previous
system settings; OTOH maybe it is meant this way to prevent tampering with
plots?

I report the 2nd issue here as well as I suspect (gamble) the two are related.
If they're not I'll gladly open a new bug report.
