complexplot examples in the help is limited.

this is a example

abs(z-a)-abs(z+a)=2c

c is a fixed,

a is a real number

a is a complex number

plot the locus.

Dear All

I am trying to substitute an expression that contains hermitian operators where the ordering is crucial. I have tried algsubs and simplify-sidderels, but they both do nothing.

I am trying to substitute;

a + b*c*b = R

where all are defined as hermitian operators in the Physics package.

into an expression;

H = - a - b*c*b

but nothing happens...

However, when I substitute a = R - b*c*b, rather than getting H = -R, I get;

H = -R + c*b - b*c*b

Ok, so for my Analytical Mechanics class, we have a problem that requires the use of Maple, Mathematica, etc to solve. I was able to get a workable solution, but getting a final answer (for initial groundspeed, as I'll describe in a minute) involved a process of guess and check, manually tweaking variables to find a close approximation. My professor's solution did much the same thing. I don't like guess and check, since I'm sure Maple is capable of doing what I need it to do automatically. So I'd like some suggestions on how to make it work. First, though, The Problem:

Hi there,

I am working through the example in maple help,

trying to save a lib (maple library)

Hi,

I have written several procedures (predefined function).

How do I make them a package?

So I just have to load it with "with(myfunctions):"

then I will be able to use thses functions.

I have had a look at

http://www.mapleprimes.com/forum/maplepackagemodule

not so sure if I understand all.

what function should I look it maple help?

Thanks in advance.

Hi,

is it enough to check wether two lists are equal using "is(a=b)"?

a:=[1,2,3,1,5];b:=[1,2,3,5,4];c:=[1,2,3,1,5];

is(a=b);

false

is(a=c);

true

the results seem fine. Do I have to check each element? I just want to be sure of it.

Thanks.

Hello there,
I was wondering, is there some way to make the following task any easier? It requires a lot of work to plot this. I want to be able to do it in maple, easily, otherwise there must be other programs where vector plotting is easier? I really want to be able to do this easier. Thanks a lot.

Also the necessary text i written below.
We have the points A(-3,5), B(-1,8), C(3,6), D(8,-4)
Draw vector AB, BC, CD and DA and determinate their coordinates.
AB = 2,3
BC = 4,-2
CD = 5,-10

Hi!

I have to use code from older Versions of Maple which is for example of the form (only much longer)

> a := proc()

> local i;

> i := 89;

> i;

> end proc;

> a();

Hi,

I was looking at this page

http://www.maplesoft.com/support/help/Maple/view.aspx?path=ImportMatrix

However, it didnt mention how to save Matrix into Excel or CSV file.

Can Maple do that?

Thanks.

Good Evening Everybody,

Would anybody show me how to subtract a scalar from each value in a list and output the results as list. Below is the problem am trying to solve, transforming the coordinate of the list to the origin (C.G). My goal is to output w =[ .....] and z = [.....]

#msub(mi("x"),mi("coord")) := [0., 2., 8., 10., 5., 5., 7.5, 7.5, 2.5, 2.5,

5.0, 5.0, 0]

#msub(mi("y"),mi("coord")) := [0., 10.0, 10.0, 0., 0., 2.0, 2.0, 3.0, 3.0,

Hi,

I am trying to save batch of data into different of files.

for i to nops(a) do

save a[i], "key_[i].m"

od;

Error, save can only save names

i.e. save each element in "a" to the file named "key_i" (key_1,key_2,key_3,ect)

how should I write the code?

Thanks.

Hi,

I remember using 'global' in the procedure as a global parameter,

however, it's not working...
