Hello to all,
I want to display two curves from six InterpolatingFunctions
{r1x[t], r1y[t], r1z[t], r2x[t], r2y[t], r2z[t]}
produced with NDSolve. The documentation describes the usage of
ParametricPlot3D for displaying one curve:
ParametricPlot3D[{fx,fy,fz},{t,tmin,tmax}]
and this works fine for me:
ParametricPlot3D[Evaluate[{r1x[t],r1y[t],r1z[t]}/.%],{t,0,dt}]
For plotting several objects together, the documentation says:
ParametricPlot3D[{{fx,fy,fz},{gx,gy,gz},...},...]
but
ParametricPlot3D[
{Evaluate[{r1x[t],r1y[t],r1z[t]}/.%],
Evaluate[{r2x[t],r2y[t],r2z[t]}/.%],{t,0,dt}},{t,0,dt}]
doesn't work at all. I tried to vary this expression in many (also
stupid) ways, without any result. What's wrong with it?
Thanks a lot,
V o l k e r
