CameraUpVectorMode resets itself to 'auto' on its own ... WHY???

In R2015b, I have a 3D plot that I want to display with the y-axis pointing straight up, the z-axis pointing down and to the right, and the x-axis pointing up and to the right. I can accomplish this by first generating my 3D plot, then calling:

az = 232.5;
el = 30;
upVect = [0 1 0];
view(az, el);
set(gca, 'CameraUpVector', upVect);

This places the axes in the orientation I want, and it sets the 'CameraUpVectorMode' property in 'gca' correctly to 'manual.'

However ... if I do anything else to the figure (like issue another view(az, el) command, or try to spin it using the manual rotation tool), the figure 'resets' itself to the traditional z-axis up orientation, and 'CameraUpVectorMode' resets itself to 'auto.'

This is clearly unexpected behavior, in other words, a bug.

Has this bug been fixed in subsequent releases?

Thank you for your feedback on this issue. We will consider this for a fix in a future release of MATLAB.

At present, "view" and "rotate3d" MATLAB functions are designed to work with 3D graphs/plots and thus reset the camera upvector to positive z-axis orientation when used.

As a workaround, to rotate the figure in any direction, please use the camera toolbar's (View -> Camera Toolbar) "orbit" button after selecting the "No principal axis" button.

To programmatically rotate the scene, use "camorbit" function along with other cam* series of MATLAB functions.
