a real vector or matrix. If omitted, it is assumed to be the vector
1:nz where nz is the
number of curve points given by the z
parameter.
y
a real vector or matrix. If omitted, it is assumed to be the vector
1:nz where nz is the
number of curve points given by the z
parameter.
z
a real vector of length nz or a matrix with nz rows.
p
a real scalar in the interval[0 1[. Default value is 0.1.
fun
a scilab function with calling sequence z=fun(x,y).
c
a vector of ny color index.
Description
If (x,y,z) are three vectors with the same number of elements, this function draws a 3D comet
animated plot. The plot is made of three parts:
ahead
mark that shows the current (x(i),y(i),z(i)) position.
abody that shows the trailing curve that
follows the head: the
(x(i-k:i),y(i-k:i),z(i-k:i))) part of the curve.
atail
that shows the (x(1:i-k),y(1:i-k),z(1:i-k)) part of the curve.
if z is a matrix and
(x,y) are vectors then animated curves
are drawn for each triple (x,y,z(:,l)).
in this case nz is the number of rows of
z.
if x,y,z are matrices with the same dimensions then animated curves
are drawn for each triple (x(:,l),y(:,l),z(:,l)).
comet3d(x,y,fun,...) computes the
z vector as
z(i)=fun(x(i),y(i))comet3d(...,p) can be used to set the
relative length of the body. k is defined
as k = round(p*nz).
