After I have opened internet explorer with Maple

process[launch]("C:/Program Files/Internet Explorer/iexplore.exe")

what command do I use to close it with maple?

 hi

I want to solve this problem

Symbolic_Matrix.pdf  

with that code

hi

I have got an eq: Curl(A)=B;

Both A and B are vectors,  for example,             

A(x,y,z):=Ax(x,y,z) _i+Ay(x,y,z) _j+Az(x,y,z) _k;
B(x,y,z):=Bx(x,y,z) _i+By(x,y,z) _j+Bz(x,y,z) _k;

can I get A as a funtion of B? if I can, how to deal with it, and if not, what other known conditions should be added to solve it?

any help would be appreciated@。@

Dear All,

I have the following data file

1.1    0.751    0
1.5    0.764    0.419
2       0.777    0.665
2.5    0.796    0.791
2.71   0.81     0.81

and I want to plot the 2nd column vs the 1st and the 3rd vs the 1st on 1 axis, with the 1st column on the x axis.

Hi,

I just purchased the personal edition of Maple 14. It was working just fine for 3 or 4 days but now the java interface is distored. Even hovering the mouse over the palettes or images causes distortions. I've uninstalled and reinstalled several times but it hasn't worked.

Has anybody else encountered this? Does anybody have a solution?

Dear all,

 I have a problem in programming with maple if statement:

 restart;Qs:=24; p:=20; m:=3; q:=Qs/(2*p*m); if (q=1) then
> yc:=Qs/(2*p); elif (frem(q,1)~=0) then if (evalf(Qs/(2*p))<1) then
> yc:=1; else yc:=floor(Qs/(2*p)); end if; else yc:=round(0.8*Qs/(2*p)); end if; 

The result is yc:=0; the result must be yc:=1;

 In Matlab:

Hello all,

I'm a new user, hopefully you can assist me as I have work on this problem for quite sometime, I keep getting error of Error, (in dsolve/numeric/bvp/convertsys) unable to convert to an explicit first-order system

I copy my work here. If anyone need the original worksheet I can send this immadiately. Please help and I would like to say Thank you.

R:= 8.31434;             ...

Compare the results of isdifferentiable on 3 piecewise defined expressions f, g, and h.

The first time the order of the asking is f, g, h. The second time (after a restart) the order is h,g,f.

The results are remarkably different! What is going on?

isdifferentiable was first brought to my attention within the last week or so, maybe it is not reliable?

If you remove all the lines with 'assuming' then the inconsistency remains.

restart;

You can   Insert -> Table (and specify the size) manually,

but how do you do that using code then have data go to specified cells?

Whenever I use polynomial fit, its tells me 'Warning: there are zero degrees of freedom' what does this mean?

Hi all,

What is the command in Maple which is equivalent to the command "mod" in Matlab ?

Thanks

Please help with the use of DEplot3d. 

Following is my script, and I kept getting the error tha looks like involving the initial conditions. 

> restart;
> with(plots); with(plottools); with(DEtools);
Setup the system of linear DEs:
> sys := [diff(x(t), t) = x(t)+y(t)+2*z(t), diff*(y(t), t) = x(t)+2*y(t)+z(t), diff(z(t), t) = 2*x(t)+y(t)+y(t)];

Setup some intial conditions

> ic1 := [seq([.1*i, .5*i, 0], i = -5 .. 5)];

There is an option box that asks you if you wish to save the calculations for further manipulation when you re-open the worksheet.  Part of the worksheet has downloaded data from a webpage.  However when I re-open the worksheet and try to continue calculations, it's like I'm starting all over again. 

There was another mapleprimes post that mentioned you need to use the command save vars as a .m file.  But since this dialogue box comes up, I didn't...

i have a maple 14 but when i plot a function i obtain large value of legend which is not suitable when i used this plot of function. i try to used the code " font = ["HELVETICA", "ROMAN", 8],this code it work.

but the code that used to change the size of legend is not work. the code is :

legendstyle = [font = ["HELVETICA", 9], location = right]);

can you please help in this problem?

Is is possible to read an image into maple located at an http location?
