error module is maple.dll_unloaded

i have already called stopmaple(kv);

in

testfunction(string hello){....stopmaple(kv));

testfunction(1);

testfunction(2);

when call testfunction again , it got error

The DirectSearch package is a powerful Maple tool. However, every soft has its advantages and disadvantages. In particular, the DS has problems in the case of a thin feasible set in higher dimensions. Recently a serious bug in the DS was detected by me. Solving an optimization problem, the DirectSearch produces the error communication

Warning, initial point [x1 = 1., x2 = 1., x4 = 2., y1 = 2., y2 = 3., y4 = 2.] does not satisfy the inequality constraints; trying to find a feasible initial pointError, (in DirectSearch:-Search) cannot find feasible initial point; specify a new one while that initial point satisfies the constraints.

I've just upgraded from Maple 15 to Maple 17, and discover that I cannot any longer write curly right braces in math mode. I use an international (Norwegian) keyboard, where curly right braces should be available by Ctrl+Alt+=, but nothing happens when I try to write this. I can work my way around it by using Copy and Paste, but this is inelegant, particularly when I want to demonstrate Maple for my class of 400 students.

Looking at older posts, I found this question, which concerns inline evaluation with international keyboard in Maple 16. Inline evaluation works fine for me, using Ctrl+Shift+=. So was this fixed at the expense of Ctrl+Alt+= ?

After disabling all security addons the Ajax gif loads, then it shows an error and after that it jumps to a page displaying "2013", but that page actually does not have any content (use ctrl + u to see it).

And the I see, that the browser tries to load from maplesoft.112.2o7.net and hangs up in that transfer (have not checked the ports).

In reality I would forbid to load from 2o7, as I receject almost all trackers.

But looking at Adobe http://www.adobe.com/de/privacy/analytics.html or others http://www.makeuseof.com/tag/that-mysterious-2o7-net-tracking-cookie-all-you-need-to-know/ those are 3rd party cookies (Omniture ---> Adobe)

Every reasonable person aware of security and xss forbids dubious sources from other websites (and I am not happy that this sites call Ajax at Google)

And if that is the reason for the bad behaviour of the new sites it would be a good joke, really.

For me it only works with IE and all its security issues (and I have to use "preview" before posting is possible)

Bug in type(HFloat(-infinity), pos_infinity). Negative infinity is incorrectly recognized as positive one:s:=HFloat(-infinity); HFloat(-infinity)type(s, neg_infinity);type(s, pos_infinity); # bug ...

Hi,

I'm computing some difficult integrals, involving Spherical Harmonics. I've proved that the answer must be a real number, and yet Maple returns a complex number. Also Mathematica returns purely real numbers, so I wonder if there is a bug in Maple. I found if I break the integrand into real and imaginary parts, and add them I get the right answer...usually. Anyway's here's the code and the proof, I suspect they could be a bug...

Theres seems to be an error in the SphericalY function when the input is SphericalY( l, -l, theta, phi)

restart;

assume(phi, real):assume(theta, real):for l from 1 to 2 do m:=-l; s:=SphericalY(l,m,theta, phi); f:=s*conjugate(s); plot3d(f, phi=0..2*Pi,theta=0..Pi,coords=spherical);#sphereplot(f, phi = 0 .. 2*Pi, theta = 0 ..Pi, style...

The second graph is incorrect. The reason?

plots[polarplot]([3+cos(4*t), 2-cos(4*t)], t = 0 .. 2*Pi)

The latest quick update fix for a bug is the fastest fix I have seen in a long time. A nice surprise actually.

In my travels I happened to come across this ... "Since then, we’ve successfully released a new build of Wolfram|Alpha’s codebase each week, incorporating not only hundreds of minor behind-the-scenes enhancements and bug fixes, but also a steady stream of major new features and datasets." taken from here

I have a very strange bug with Maple 16. When I try to start it, Maple loads its shell and starts to consume 100% CPU (maple.exe, not mserver.exe). If I try to calculate something, it throws something like "waiting for server connection". In 3 to 10 minutes Maple suddenly stops doing this and then works normally until I reboot Windows. What's this? Maple 16.0, Windows XP SP3.

PS. I do not have such bugs on my home PC with Windows XP SP2.

People:

I wrote a Maple 15 worksheet containing a function that calls two other functions defined earlier in the worksheet. The main function didn't work, so I replaced one of the functions that was called, by cut-and-pasting its definition into the main function. This is obviously inconvenient because I want to alter the function that I cut-and -pasted and whenever I do it I will have to cut-and-paste again. It also detracts from the...

is the series expansion for the following expression bugged in maple or am I missing some crucial thing of series?

series((1/epsilon-log(4)),epsilon=0);

results in epsilon^-1 -2 -2*ln(2)

for xmaple 16.01. The console version does not add the wrong term "-2".

Apparently it works here:

Hello,

I just lost the result of a 20h calculation due to the last-name evaluation using tables. Consider that

t := table([1=2]):

s := t:

save s, "table":

restart:

read "table":

s[1];

evaluates to t[1]. The save command only...

The version 16 of Maple does not know the function "pow", it is replaced by "power". Nevertheless, the codegen[optimize] procedure still generates it! Moreower, it's not optimal even to write poser(..., 1/2) as, most probably, the function sqrt must run faster.

Here's an example: (the function being optimized just contains some nested square roots)

> iang10 := [codegen[optimize](Re(int11), tryhard)];[ 2 t17

I'm having an issue with the implicitplot3d command in Maple 16. The sequence of commands I've listed below works just fine in Maple 15, but in Maple 16 I'm getting a problem. Sometimes no graph will display; other times, Maple may initially graph the surface correctly, but as soon as I rotate the graph, the surface disappears. Furthermore, the following strange things happen:

1) Re-executing the command after rotating does not redraw the image ...
