What's the difference between VerticalBar and VerticalLine?

 

we have:

x = c[2]*e/c[1]+(2*c[3]*c[1]-3*c[2]^2)*e^2/c[1]^2+(3*c[4]*c[1]^2-10*c[2]*c[3]*c[1]+8*c[2]^3)*e^3/c[1]^3

how can we find a function "F(x)" the first three terms of whose power series around "e=0"  is given as:

1+c[2]*e/c[1]+(2*c[3]*c[1]-c[2]^2)*e^2/c[1]^2

Hello,

I'm try to access some external Fortran routines within maple. I have a Fortran datatype of

  character*255 hf(20)

This is an input parameter, and I believe this will map into a maple Array object, but I'm not sure of the datatype. The help says that the datatype can only be "hardware datatypes" so I take to mean it would have to be of type integer[4]...when I do this I get the error below.

Hello,

I am interested in computing the image of a constructible set in Maple.  I am using Maple 12 on a remote machine.  I am able to load the ConstructibleSetTools, ChainTools, and RegularChains libraries.  This paper indicates that the authors were using Maple 12 and have defined the RationalMap command.

Hello,

Just a question about presentation.

If I have  a program like this:

for i to N do
for j to N do
i+j
od;
od;

How to show it like this?

for i to N do
   for j to N do
        i+j
    od;
od;

I have tryed some compositions with the keyboard but "everything doen't work".

Many thanks,
Ternox

Very few people would ever need this, I think, even while programming. But sometimes the details of the call stack are just what one wants.

So, for example,...

> h:=proc(x)
>   debugopts('callstack');
> end proc:

> m:=module() export f; local g;
>   f:=proc(x)
>     g(x^2);
>   end proc:
>   g:=proc(x)
>     global h;
>     h(x^3);
>   end proc:
> end module:

> m:-f(a);
[DEBUGSTACK, h, `debugopts('callstack')`, [a^6...

How do i code into maple to check if a matrix is diagonally dominant?

s:=Matrix([[2,1,2],[-5/4,-5,5/4],[21/5,-14/5,7]]):
 

s[1,1];

2

s[1,2] + s[1,3];

3


this is what av done so far but i dont think its correct

for i from 1 to 3 do
for j from 1 to 3 do

s[i,i] <= s[i,j] + s[i,j+1]

hello everybody,

Just a little question about lists.
I have a result like this

Result := {alpha[2] = -1.536774530, alpha[3] = -2.345615736};

How to select -1.536774530 and -2.345615736 ???

If I do Result[1];     it return alpha[2] = -1.536774530.

 

Many thanks !!!

Hi,

How do I label something without having to have maple evaluate it first?

For instance I would like something like this

 

to be labeled on the right side, when i try it just retuns false.

I defined five functions f[i] and three functions u[j].

Afterwards I integrated f[1]*u[1] for x=-infinity..infinity and defined it as E[11].

Then I defined an equation eqn[11] := E[11] = u[1]

Last but not least I solved eqn[11] to x. So far my doing was none of a problem and produced the expected result.

 

Then I wanted to let maple do this procedure with all combinations of f[i] and u[j].

So I wrote the following nested for loops:

I want to integrate a function which includes a proc. For example

P:=proc(t,w::list)

local v;

v:=choose an element from the list w, according to the value of t

return v

end proc

and my integrand is like this:

F:=(a,b,c,d)->a*b*c*P(d)

I'm trying to get a plot of f(x)=x^1/3 that shows the plot line (i.e. f(x) values) for x<0.  I can get the graph to show the entire four quadrants, but not plot the values for x<0.  Any help would be greatly appreciated, as I just purchased the student edition.

Thanks!

I have a problem i am trying to see how long it takes for my program to give a solution but the time keeps on changeing everytime i press enter. I can't seem to understand why?
 

I've been working with fsolve and I'm having the following issue: fsolve({dif_Fliq=((nFsol-nFliq)/(psi_sol-psi_liq)),dif_Fliq=dif_Fsol},{psi_sol=0.1..0.9,psi_liq=0.1..0.9}); {psi_liq = 0.4447971078, psi_sol = 0.3459845910} how do I get the value of psi_liq and psi_sol and assign them to a different variable without having to copy the whole thing? i.e. if I use the following command assign(result_liq,psi_liq); I get result_liq=psi_liq = 0.4447971078 not what I want result_liq = 0.4447971078 I also tried: result_liq:=psi_liq and I ended up with the same result

I am going to export formulas from maple to plain texts like this sample ! Download 11273_plain.txt
View file details but , i confused about this simple job , please someone disabuse me , how can i do it ?
