[scilab-Users] Plotting three dimensional vectors

[Stephane Mottelet]

Hi,

This can be done, but not directly. You have to plot the (x,y)  
component first using xarrows, get the handle of the segs entity then  
add a third column to the
data field :

xarrows(nx,ny)
h=gce();
h.data=[h.data nz(:)];

nx, ny, nz are 2 x n matrices containing the origin of vectors on the
first line and the extremity on the second line.
