How I could do "streamslice" makes slices with absolute or normalized values?

Subject: How I could do "streamslice" makes slices with absolute or normalized values?

   I'm using streamslice to plot magnetic field lines produced by a moving charge. To do so, I chose 3 slice planes, perpendicular to the trajectory.
   The problem is that streamslice automatically re-normalize the density of lines in every plane instead of show how the density of lines decreases as the charge moves away from a slice plane.
   I didn't see anything about it in Matlab help, so, can anybody help me?

Gustavo,

I read your thread, but I have never used streamslice. Thus I only could do little more than pour over the documentation, like you probably already did. About the only thing I could suggest from reading your post is to try and figure out what normalization factor is used, then unapply it. Otherwise, wait for someone else to come along who does know how to use streamslice, please don't ask for help on your question in another person's thread.

Thanks! And.... sorry... I'm desperate.. and I felt unattended.. I know you are an expert, so I do that.

Well, this is a usenet group of volunteers, totally unorganized and
nothing official despite the interface web site TMW has provided that
many (but certainly not all) use.

It may be there isn't anybody who sees your question that does have an
answer; hopefully that won't be the case but there's no guarantees.

It won't help your chances now nor in the future to try to to be pushy
or show impatience, etc., ... About the best one can do is to wait
patiently for at _least_ a full 24-hr day and then if nothing happens
try recasting the question. Sometimes the problem is nobody knows what
one is asking owing to language barriers, unfamiliarity w/ subject
matter, inexperience in ML leading to awkward or misunderstood
terminology, etc., etc., etc., ...

I've never used streamslice() either (couldn't have told you there _was_
a streamslice function even :) ) but it is an m-file so you can read the
code to see if you can tell where it does some renormalization and
perhaps modify it to your purposes. (Obviously copy the original into a
working subdirectory and make your modifications there and use the
modified copy rather than mung/experiment on the distribution version.)

HTH...

Thanks Thanks! I see....
