If i have to solve the eq. i have to guess what U2 is  until i get close to U1 that the error is ok. can i do this in maple. or du i have to make program.

Hi,

Recently a a simple problem which i can not handle by myself, made me confused.

I have simple code of maple which is not stable at all. Everytime I run the code, the final result which is the determinant of a matrix, changes and I can not see the problem with the code. In fact i noticed that problem occures when the matrix is being build by culculating the coefficients of some constant values.  I have attached the code. Could you see what is wrong here?

Thanks by the way.

Hi,

The default way a prompt shows on my maple is

[> blah blah blah

but i see in many worksheets including maple help pages that it shows as

> blah blah blah

My Question is how do i remove that left square bracket "[" from appearing ?

   Hi, there

 I work with maple 13 and made a file that its contet is plotting curves and its size is 

151 MB.Now when I want to open it the file cannot be opened completely only about a quarter of its contents rises.

Thanks for your help

hi, is there a way to change color of the page in Maple 18? in fact I am preparing my lectures using slideshow option and want to change the color instead of the default white.

Hi guys,

       I have the following Lagrange function. 

       (Note :w is the generalized co-cordinate.) 

       L := (diff(w(r, t), t, r))*v(r, t)

       ( I know

        If L =diff(w(t),t)*v(t)..... I can write EulerLagrange(L,t,w(t) but I dont know how to handle above function)

        Thanks in advance!!!

I am having issues opening my final year project, it was working an hour ago and now it will not open. When I try to open the file it brings up a box title TEXT FORMAT CHOICE with the options: MAPLE TEXT, PLAIN TEXT, MAPLE INPUT and CANCEL.

This is all my work and I need it to complete my year.

Any help with how I can rectify this would be extremely helpful.

Many thanks

Hi

I am trying to optimize a 39, 1 MATLAB matrix, but cannot seem to get a result beyond a 6, 1 matrix. I am getting "Warning, cannot resolve types, reassigning t##'s type" where t## varies from each time I run it, and can show multiple of these warnings. It also says "Warning, cannot translate list".

I found a pretty similar problem posted here earlier, where the user "Carl Love" suggested to replace a command from the original code with

Matlab(
     subsop([-1,1]= J, eval([codegen:-optimize](tmp, tryhard), pow= `^`)),
     output = string, defaulttype = numeric
);

I was wondering what exactly this command does? Can I apply it to my code to solve my problem? It yielded a result that looks (on the surface) as an optimized code, but I don't feel completely comfortable using it without being certain.

What I have done is simply to replace Matlab(tmp, optimize) with the suggested code above. My code is attached. Thanks in advance for any help.

Hi,

I'm, trying to write a nested loop in maple, but I keep getting the Unterminated Loop error. I'm sure the solution is quite simple, but I haven't been able to find it. Any suggestions would be much appreciated. The loop looks like this:

i:=0:
di:=25:
n:=1:  

while (n<=nLimit) do
sol1:=fsolve(eq1, y=i..i+di)
     if type(sol1, numeric) = true then
     lambda(n) :=sol1
     i:=i+di
     n:=n+1
     else  i:=i+di
     end if:
end do:

The physics package is pretty awesome, but one thing that would be a big help is some functionality for entering and resolving vectors in angle/magnitude format (50 angle 45 degrees, or what have you.) Is there a way to do this?

Thanks

Hi,

     I want to know what K1 and K2 means in the answer after using Euler Lagrange command.

     Thanks in advance.

Hej hej,

is there a way to obtain confidence intervals for the parameters in a NonlinearFit? To give you an impression of the problem which I was working on, I created a minimial working example (not sure wheather that actually helps). In this particular case, I have two parameters to fit the coefficients of a binomial series to some data I obtained. Beyond the values of the parameters (in a least square fit), I'm also interested in some kind of confidence interval, to get a feeling about how realiable my values are. Is there a direct (or even indirect) way to obtain such a thing. Either directly as a Maple function (confidenceintervals is not supported for NonlinearFit, if I'm not mistaken) or as something I can implement myself (within a reasonable time frame, as in hours rather than days).
Thanks in advance!

Cheer,

Dear Community Members,

We have problem with calculation in Maple v11 and v18. when we make a calculation by using maple v11 and v18, we was not able to get the solution as you see enclosed. when we clicked to "enter + ; ", programme does not run.

Dear all

I want to know, how one can install third party package into Maple13, the package is "wkptest" i downloaded it from link http://cpc.cs.qub.ac.uk/summaries/ADTY. If anyone knows how to do this please help.

When I create a component, here a label component, and set a name property and then click OK, that name seems to go into some list never to be erased. If I then delete the first name and put in a new name and click OK. thus saving it, and the then try to use that name again on a different component, I am told that the name is already in use. Well, no existing component has the name, but it is still in Maple's list of components. If I go to edit an action for any component and input %+command completion, I get a list of components which includes the deleted name which does not belong to any existing component. Since the name is on this list, I cannot reuse the component name.

How do I clean up this erroneous list of component names, so that a mistake in naming one component doesn't forever prevent me from using it on the component for which it was intended?
