Hello,

in my former 32bit XP usually I got this issue when the RAM was full. It would take minutes to get through.

Then today I had this in Maple 17 on Windows 8.1 x64 when I was trying to evaluate some lengthy stuff containing exp-tan-sin. Killed mserver, hoping to be able to save the file, but the Maple window had frozen as well.

Also I observed Maple consuming 14% of the RAM (which is 8GB) when the bottom line of my worksheet only displays 270 M.

In Mathematica, I can save the file in the middle of an evaluation. I'd appreciate Maple to have this feature as well.

Greetings

@Carl Love Works fine. About darkblue: I had darkblue := COLOR(RGB, 0, 0, .5): because I didn't know about "DarkBlue".

Hi,

just tested with Maple 17 (Windows 8), it produces the same result.

 

What I tried: first forget that it all should be integers

s:=[solve(5*x^2+11*x*y-5*y^2=11)];
            s := [{x = -11/10*y+1/10*(221*y^2+220)^(1/2), y = y},
                  {x = -11/10*y-1/10*(221*y^2+220)^(1/2), y = y}]

Then I evaluated the solution for integer values of y

map2(simplify@eval,s,[seq](y=k,k=0..20));

I get x=-8,y=3 and x=7,y=18 among a lot of non-integer solutions.

The second one comes if I do i=10..20 in JoeRiel's solution, but the first one didn't come.

Firefox doesn't jump to the bottom whereas Internet Explorer does. This also makes loading of the forum threads faster.

In Internet Explorer I have to click into the text with the mouse and hit "Home" (or "Pos1") on my keyboard to get to the beginning of the thread.

This should be changed because I suppose most maple users use usb mouses rather than PS/2 ones.

By the way: In Maple 10 classic I cannot use the scroll weel but I can scroll with my touchpad.

In Standard Worksheet Maple 10 I type

sqrt(5);

   sqrt(5);          (1)

Right click on (1) and "Apply a command", I typed "sin"

sin((1)) works.

then I did  (1)/((1)+1); and the kernel connection gets lost.

The same happens in Maple 10.04 Classic under Windows XP.

It says:

Execution stopped stack limit reached
The kernel has been shut down...

 

Thanks. Your plot command does exactly what I need.

Thanks for all that, it works now. I didn't know that it would be so easy and I usually hate all those tilde signs when using assume with long results.

The shortest code is now l:=convert(Eigenvalues(K),list); Vector(l), eval( convert( map(lambda->LinearSolve(K-lambda*IdentityMatrix(2),<0,0>,free=s),l), Matrix), {seq(s[i]=1,i=1..2)} ); It works just like solving with "Eigenvectors" should have worked.
