Does anyone know why I'm seeing these errors? I'm not giving it a matrix.

>>> t = 0:0.1:2*pi;
>>> quiver3(4*t,3*cos(t),3*sin(t));
error: __quiver__: operator +: nonconformant arguments (op1 is 3969x1, op2 is 6
3x1)
error: called from:
error:   /usr/share/octave/3.6.2/m/plot/private/__quiver__.m at line 179, colum
n 10
error:   /usr/share/octave/3.6.2/m/plot/quiver3.m at line 75, column 11

    $\begingroup$ You're not even saying what programming language/math system this is. A bit more context would help! $\endgroup$ Sep 30 '13 at 3:11

Matlab is a bit more explicit than Octave:

quiver3(4*t,3*cos(t),3*sin(t))

??? Error using ==> quiver3 at 53

Not enough input arguments.

There is no way of using quiver3 with only 3 arguments. What did you want to do?

  • $\begingroup$ Ohhh I see what Im doing wrong, I have to include the derivatives for them. quiver3(4*t,3*cos(t),3*sin(t),4,-3*sin(t),3*cos(t)); $\endgroup$
