Hi

The example below is the same as my code:

restart:with(Optimization):f:=(a+2*b+c*d)*sin(wr*p*t);

fmoy := p*wr*(int(f, t = 0 .. Pi/p/wr))/Pi;

fmax:=NLPSolve(f,t = 0 .. 2,a=1..5,b=0.1..0.5,c=0.4..0.8,d=10..20,wr=200..300,p=5..20,maximize);

fmin:=NLPSolve(f,t = 0 .. 2,a=1..5,b=0.1..0.5,c=0.4..0.8,d=10..20,wr=200..300,p=5..20);

Taux:=NLPSolve((fmax-fmin)/fmoy,t = 0 .. 2,a=1..5,b=0.1..0.5,c=0.4..0.8,d=10..20,wr=200..300,p=5..20);

As shown in the image bellow. The first statement of fsolve function yields nothing but evaluating the expression. I copied the expression into the second command line and got the result. How can I make the first one works, since it belongs to a proc in my program. 

Hi

I have some difficulties in manipulating matrices in Maple

For example, I have a matrice with 40 rows and 9 columns ans I want to extract the odd rows taking columns inchanged. The new matrice which has 20 rows and 9 columns must replace the old matrice

In Matlab, I do this with only one command: WTable=WTable(1:2:40,:);

Thanks in advance for help

Hello,

I am just now learning how to use Maple and I am having trouble turning Ohm's Law into a function.

Here is what happens when I try to turn Ohm's Law into a function.

V_rms:=(R,I)->R*I

       Error, invalid operator paramet name (and then it puts a dotted red line box around everything to the right of the equal sign)

What really irritates me is that I can type

Hi

In matlab we have this command:

I = FIND(X) returns the linear indices corresponding to the nonzero entries of the array X.

[I,J,V] = FIND(X) also returns a vector V containing the values that correspond to the row and column indices I and J.

Is there a command in Maple like "find" in Matlab

Thanks in advance

Hi,

imagine I have the following line:

(y/2)*(4/3)*sin(x);

can I tell Maple not to merge everything together? I want to have it all seperated, like a separate fraction for y/2 another for 4/3 and then comes the sine, with small spaces between them, indicating multiplication.

thanks.

I have a maple worksheet with 2d input:

> for i to 10 do f := proc (x) options operator, arrow; x^2 end proc; f(x) end do;

of course it looks "pretty" in the actual worksheet.

When I export this to Latex I get the standard stuff and this:

\begin{maplegroup}

\begin{mapleinput}

\mapleinline{active}{2d}{for i to 10 do f := proc (x) options operator, arrow; x^2 end proc; f(x) end do; -1}{\[\]}

This first example command

solve({(x-1)/(2*(x-2)) = 2/(x^2-4)+2*(1/2)}, {x})

will be x=-1.

The second example command

solve({(x-1)/(2*(x-2)) = 2/(x^2-4)+1/2}, {x})

won't give me any answer. I know that there is no solution (in sense x=2 for example) for the second math problem.

How can I tell mapple to show me that x=2 ? (even if it's not inside the definition sum R)

Or, if the simplyfication of the equation would be something like x = x + 2 ...

Hi all,

How can I write a vertical etiquette (title) in parallel with y axis ?

How can I give a legende inside the plot (inside Figure) ?

How can I make symboles for different curves ?

Thanks in advance

Hello!

Since a few weeks i use Mac OS X, I downloaded the accordingly maple version from my campus server and installed it. I can start the program, but when I enter a simple instruction like plotting x^2, I get a little progress window with the headline "Kernel Connection Not Available", in the window there is: "Waiting for kernel connection" with a status bar and a Cancel-Button. The status bar runs through until about 60% and then it doesn't go on.

Can you...

Dear Maple users

I use Maple in my physics class in high school. In connection to that I have stumbled on a couple of oddities with the new version 14:

It looks like a bug, that Maple...

Hi folks,

i am brand new to Maple so please excuse if i ask a probably simple question:

Is it possible to get data from the first row of an array into a DropDownBox?

I created an array named mat, if i type something like test:=mat(2..,1) Maple shows me the information i need in a column.

Now i want to create an Element (DropBox) in which i want to select data from a list that should show me the same information as the...

Hi,

I try to find minimum value for numbers as follow,

for i from 1 to 1000 do

x:= 1+i; 

y[i]:= 2*x+1;

a:=min(seq(y[k],k=1..1000));  print(a); od;

in this case the maple can not provide any solution

however, when i use 100 instead 1000 i obtain result as follow,

for i from 1 to 100 do x:= 1+i;  y[i]:= 2*x+1; a:=min(seq(y[i],i=1..100));  print(a); od;

could you please help me to solve this problem?
