thank you!

thank you!

Once again I'm sorry; and this time I'll try to be more cautious:

What I want to do is to assign the solution so I can plot the phase space, which means here the solution x(t) in abscissa and its derivative in ordinate.

Any idea how to do that?

Thanks a lot for your precious help hirnyk 1624 that's exactly the plot I need.

I have one last question though:

How can I define a "function solution" so that I can plot diff(x(t),t) depending on x(t)?

thanks again!

I apologize:
I am realising I didn't ask the correct question ...

In fact I don't want to plot a vectorfield:

actually I defined a vector B(x,y,z) for each point (x,y,z).

My question is the following:

How can I get Maple to plot in the space these vectors that depend on the points (x,y,z)?

I'm sorry about my former post, I didn't notice your name was written below your title and I'm confused since I thought this title was your pseudonym.... I read the article you recommended me... I didn't mean to offend you.


Best regards.

Hi one way

I suceeded ploting a field with "one vector" but I didn't manage to plot "all of thme".

Here is the point:

I have a list of vectors A that is sound to represent my magnetic field B for each point of a plan z constant . Each component of A gives (x,y,B(x,y)) and I'd like to represent B for every point. 

I tryied   VectorField(<2,3,4>,<3,4,5>, output = plot)  hoping it would represent these two vectors in different plces for instance but it didn't work. 

Do you know how I should do it??

Thanks a lot it seems to work.

And if I understand well the difference between Re() and fnormal is that fnormal selects the numbers and if they are complex (and non real ) and their imaginary part is "negligible" then it removes it, whereas Re() computes the real part of any number (and therefore takes more time)???
