Question: Use DEPlot3d

Please help with the use of DEplot3d. 

Following is my script, and I kept getting the error tha looks like involving the initial conditions.

Setup the system of linear DEs:
> sys := [diff(x(t), t) = x(t)+y(t)+2*z(t), diff*(y(t), t) = x(t)+2*y(t)+z(t), diff(z(t), t) = 2*x(t)+y(t)+y(t)];

Setup some intial conditions

> ic1 := [seq([.1*i, .5*i, 0], i = -5 .. 5)];

> ic2 := [seq([0,0.3*i,0.5*i], i=-5..5)];

> RHS := eval(map(rhs, sys), [x(t) = x, y(t) = y, z(t) = z]);
                    [x + y + 2 z, x + 2 y + z, 2 x + 2 y]
> fieldPlot := fieldplot3d(RHS, x = -1 .. 1, y = -1 .. 1, z = -1 .. 1, grid = [5, 5, 5], axes = boxed);

> dePlot := DEplot3d(sys, [x(t), y(t), z(t)], t = 0 .. 10, {ic1, ic2}, scene = [x(t), y(t), z(t)], stepwise = .1, linecolor = blue);
Error, (in DEtools/DEplot/CheckInitial) invalid initial conditions - must be list of lists of conditions
> display(fieldPlot);

 

Please Wait...
