xarrows
draw a set of arrows in 2D or in 3D.
Calling Sequence
xarrows(nx, ny [,nz] [,arsize, color])
Arguments
- nx, ny, nz
real vectors or matrices of same size.
- arsize
a real scalar, size of the arrow head. The default value can be obtained by setting
arsize
to-1
.- color
a matrix or scalar. If
color
is a positive scalar it gives the color to use for all arrows. If it is a negative scalar then the current color is used. If it is a vectorcolor(i)
gives the color to use for arrowi
.
Description
xarrows
draws a set of arrows
given by nx
, ny
and nz
.
If nz
is not given, then the arrows are drawn in 2D.
If nx
, ny
and nz
are vectors,
the i
-th arrow is defined by
(nx(i),ny(i),nz(i))-->(nx(i+1),ny(i+1),nz(i+1))
.
If nx
, ny
and nz
are matrices:
nx=[xi_1 x1_2 ...; xf_1 xf_2 ...] ny=[yi_1 y1_2 ...; yf_1 yf_2 ...] nz=[zi_1 z1_2 ...; zf_1 zf_2 ...]
the k
-th arrow is defined by (xi_k,yi_k,zi_k)-->(xf_k,yf_k,zf_k)
.
xarrows
uses the current graphics
scale which can be set by calling a high level
drawing function such as plot2d
.
