Using worksheet mode. It is a strugle to add a new paragraph on its own group so I can document some code.

I open new worksheet, and type a Maple command. say

x:=10; and hit return.

Now the screen looks like

------
|>x:=10;
|                        x:=10
----
|>     curser is here now    (1)

Now I want to make new paragraph, on its own group, before I type new command. (I need it on its own group, to fix another Maple latex export issue) i..e I want it to look like

------
|>x:=10;
|                        x:=10
----
|   this is pargraph I wanted to create
-----
|>     curser is here now    (2)

However, this is not possible using one command.  when in (1) above, if I tell Maple to insert paragraph->Before cursor, it does this:

------
|>x:=10;
|                        x:=10
----
|  it created a paragraph- here, but this is still in the same group as (1) below
|>     curser is here now    (1)

Only way I found to do it is this: create an execution group before the cursor. Then go back to that execution group. Then do insert paragraph->Before cursor, then delete the execution group just created, leaving the paragraph on its own group:

Step 1

------
|>x:=10;
|                        x:=10
----
|> create this as execution group
----
|>

Step 2

------
|>x:=10;
|                        x:=10
----
|   create paragraph here
|>
----
|>

step 3, delete the execution group, leaving the paragraph

------
|>x:=10;
|                        x:=10
----
|   leaving paragraph on its own here
----
|>

there got to be a simpler way? I am using Maple 18 on windows 7. (64 bit)

Maple 18, windows 7.

When I export this to Latex

x:=1/y;

The latex comes out as x:=y^-1 instead of using 1/y as it displays. I prefer 1/y and not  y^-1

i.e. instead of generating {y}^{-1} it should use \frac{1}{y}, just as it appears on the screen. Is there a configurration option one can use for this?

I also like to know if one can insert latex markup directly in Maple text paragraphs?

For example, if I add a text paragraph, (Menu->Insert->Paragraph) and would like to type some math in there, I can't just write $\sin(x)$ as this will not render as math when exported to Latex, as it is in a Maple normal group in the Latex file. 

Is there another way to typeset math in text area of a document? I only use worksheet mode. Not interested in using document mode.

thank you

AOA... I want to convert system of equations into matirx form.

F[0] := u[0, n]-u[0, n-1]+u[1, n]-u[1, n-1]+u[2, n]-u[2, n-1]+u[3, n]-u[3, n-1]

F[1] := u[0, n]-u[0, n-1]-u[1, n]+u[1, n-1]+u[2, n]-u[2, n-1]-u[3, n]+u[3, n-1];

F[2] := u[0, n]/P-u[0, n-1]/P-.7071067810*u[1, n]/P+.7071067810*u[1, n-1]/P+.7071067810*u[3, n]/P-.7071067810*u[3, n-1]/P+0.4549512860e-1*exp(-1.*t)-.3431457508*u[2, n]+.3431457508*u[2, n-1]+1.556349186*u[3, n]-1.556349186*u[3, n-1] = 0;

F[3] := u[0, n]/P-u[0, n-1]/P-.7071067810*u[1, n]/P+.7071067810*u[1, n-1]/P+.7071067810*u[3, n]/P-.7071067810*u[3, n-1]/P+0.4549512860e-1*exp(-1.*t)-.3431457508*u[2, n]+.3431457508*u[2, n-1]+1.556349186*u[3, n]-1.556349186*u[3, n-1] = 0;

I want to export the above system of equation in to matrices of as

AU[n]+BU[n-1]-C = O;

where*U[n] = Typesetting[delayDotProduct](Vector(4, {(1) = u[0, n], (2) = u[1, n], (3) = u[2, n], (4) = u[3, n]}), a, true)*n*d*U[n-1] and Typesetting[delayDotProduct](Vector(4, {(1) = u[0, n], (2) = u[1, n], (3) = u[2, n], (4) = u[3, n]}), a, true)*n*d*U[n-1] = (Vector(4, {(1) = u[0, n-1], (2) = u[1, n-1], (3) = u[2, n-1], (4) = u[3, n-1]})), Help me plz;

how to transform

Matrix([[1,0,0],[1,0,0],[0,0,0]])

to

Matrix([[0,0,0],[0,0,1],[0,0,1]])

so we have to Write a maple function with -> that takes an integer N and a boolean function

F: {(i,j) l 0<= i,j<= N} -> {true,false} 

and returns a list containing all [i,j] such that F(i,j). A procedure that does this
would be

proc(N,F) local i, j, RV;
RV:=NULL;
for i from 1 to N do for j from 1 to N do
if F(i,j) then RV:=RV,[i,j] ; end if ;
end do ; end do ;
return RV ;
end proc ;

The problem is to do this inline, i.e. you have to write
(i,j)-> ...

please help...

int(sin(x)^cos(x),x= 0 .. Pi)

with Maple? A closed-form answer is also welcome.

Thank you for your help with this question. I found what I was looking for. 

I am trying some data analysis on an Excel worksheet using Maple. I have the following procedure but I don't know how to make it work for a specific subset of cells (this is a psychological studiy, so I want to have all my scores for each subject, located on the rows, and variable, located on a subset of columns). Example: I want to get an array of all the average scores in a rectangle of cells which goes horizontallyfrom A to AB, and vertically from row 1 to 15. Hope you can help me out! Cheers!

MediaRighe := proc (M) local i, j, r, c, S, N; r := LinearAlgebra:-RowDimension(M); c := LinearAlgebra:-ColumnDimension(M); S := Array(1 .. r); for i to r do S[i] := 0; N := 0; for j to c do if M(i, j) <> "-" then S[j] := S[j]+M(i, j); N := N+1 end if end do; S[i] := S[i]/N end do; return S end proc

I also have this for the columns (same thing, basically):

MediaColonne := proc (M) local i, j, r, c, S, N; r := LinearAlgebra:-RowDimension(M); c := LinearAlgebra:-ColumnDimension(M); S := Array(1 .. c); for j to c do S[j] := 0; N := 0; for i to r do if M(i, j) <> "-" then S[j] := S[j]+M(i, j); N := N+1 end if end do; S[j] := S[j]/N end do; return S end proc

Thanks everybody!

I am interested in using both in the same graph. And I am aware that i can drag from one to the other manually, but I am interesseted in doing it in a command. 

So i have 3 vectors a, b and an error. 

I can define ExponentialFit function based on a and b, and the plotting both observations, errors and the fitted function.

I know how to find a solution that satisfies the constraints, but in my case I need to find a solution which does not satisfy the constraints. Is there anyway that lp_solve can do that for me?

Lets say I have the following in LP format:

max: a;
1 < a;
a < 10;

Then, I can use lp_solve to give me a solution satisfied by the constraints, but is it also possible to find a solution not satisfied by the constraints using lp_solve?

Is there a Mangoldt function in maple? How do you invoke it?

I plot a curve with "plot" command, how to export the figure to .emf format file?

Please advise as to the proper coding entries needed in the triple integration palette  to transform from the Cartesian placeholders x;y;z to spherical coordinates rho; theta; phi so that the triple integration palette can be used in spherical coordinmates. Dr. Lopez alreadyb has a standalone template which does this but I would like to set a palette option for spherical  calculations.

Thanx

This is one of these silly ones that crop up every-so-often (and yes, beta, gamma are just the relativistic v/c and energy):

gamma=1/sqrt(1-beta^2);
solve(%,beta);

comes up with ±I*sqrt(-gamma^2+1)/gamma.

While this is not wrong it is nothing I want to throw at any student trying hard enough as it is to keep his/her head above water. What I want is beta=sqrt(1-1/gamma^2) and I am having a devil of a time getting Maple to do this. even doing it "by hand" the I comes in the moment I take the sqrt. "assuming" does not help (and when I try ...assuming beta::positive, gamma > 1 I get an error claiming these to be inconsistent).

What gives?
