I'd like to ask you about line 28 in structure_tensor_plot.m :

[stheta, sphi, srho] = cart2sph(e3(1), e3(2), e3(3));

Why did you use e3 instead of e1? since l1 >> l2 = l3 (aprox.) , it should be e1 that corresponds (l1). I would appreciate a lot if you answer my inquiry.
Thanks in advance.

There is a bug on line 71. It should be:
cylinder(coneRadius:-coneincr:0);

Otherwise, the base radius of the cone does not vary with the 'coneRadius' parameter above.

Also, it should be sufficient to use

incr = 1

on line 69

Thanks for the useful function
