I have asked this question in a math forum on the physics forum site and figured it would fit better here:

any and all help would be greatly appreciated!

can any one help how to plot streamlines for any given velocity vector field. or any one know strean proc please.

I have given a hypercube in dimension d > 3 (in the form (min,max) for each coordinate) and I want to get all integral points in (LaTeX-Pseudo-Code):

Z^d  \cap hypercube

ie. I want to compute all integral coordinates which are in the given boundaries. In d=3 this is easily done by three for-loops. But how in general dimension?

Hi, I have plotted an implicit 3d plot of an extensive equation into maple, but the particular equation represents a treshold, as it is calculated as the difference between two equations. Which means that everything below the graph represents the case were equation one is bigger than equation two and everything above the graph the opposite. Now by changing the parameters held constant before, I would like to make clear what happens to the chance that one equation is bigger than the other. So to come to the point, is it possible to calculate the surface below and above a certain graph?

Hello,

I am trying to work with nested procedures, and I am getting weird results.  Maybe I am going crazy, or I am doing something wrong, or this is just a bug.

I've reduced the problem to this:

I'm having trouble entering text in maple 10.  I enter a sentence, then go to enter a formula and get an error message. I just want to use maple to enter formulas with explanation.  Is there a article on how to do this?

Just curious as to what things mathematica is better at than maple?  In other words what does mathematica have that maple doesn't?  Are they better at graphic visualization?

I frequently end up with large equations with many repeated sub-expressions.  These equations could be made infinitely more readable if this one expression were broken up into several expressions to calculate the sub-expressinos and store them in auxiliary variables.  This is not just good for readability...it is also useful when it comes time to move the results into a programming implementation (Maple is just a playground).

i want learn programming with maple

would you help me with lecture notes 

thanks

I get a strange error: I'm calling a procedure f( L1 , L2 ) which expects two lists L1, L2 as parameters such that each entry of L1 and L2 is of type 'rational'.

This procedure is called several times but from time to time this error occurs:

"Error, (in  ....[f]) invalid input: ....[f] expects its 1st argument, L1, to be of type ......, but received [0., 1, 0]"

Does Maple do some kind of auto-conversion of e.g. L1=[0,1, 9999999 / 10000000] to the corresponding float?

Sorry for posting something similar again on computing on multi-core-machines but it's really important.

So the question is:

There are two possibilities for solving a problem:

(a):
f := proc(L::list)

r1 := g( first part of L );
r2 := g( second part of L );

return [ op( r1 ) ,op( r2 )]:
end proc:

(b):

How can I write a Maple program (using if..else) to find the first positive integer n (between 1 and 355)such that 355 can divide n*m (m is an integer, say 199) ? Thanks for your help.
