This is a specific Maple 2016 question: I find that plots no longer remember their attributes (like size on the screen) upon re-execution of a worksheet, even though I have set the appropriate flag in the Interface pane of the preferences.

Can someone confirm this; or am I just being dense? Is this an OS X issue? An El Capitan issue?? Maple 2015 on Yosemite behaves as expected.

Maple 2016.1 on Mac OS X 10.11.5.

Thanks,

M.D.

Hi to all.

Is possible to use Maple in Excel ? How ?

Where can I search a brief description of Maple's product ?

Thanks

 

 

 

 

how to convert GeneralLinearGroup and GeneralOrthogonalGroup to permutation group for small parameters 

 

GL23 := GeneralLinearGroup(2, 3);

Generators(GL23);

i use generators , is it correct to find permutation group?

but there is a comma,

[((1, 2)(3, 5))(4, 7), (1, 3, 6)(2, 4, 8)]

does it mean that it has two different solutions?

if not, it is only one solution, 

does it mean that permutation matrix is 

permutationmatrix of  ((1, 2)(3, 5))(4, 7) + (matrix plus) permutation matrix of  (1, 3, 6)(2, 4, 8) ?

Dear All

I have 3D plot

How I can Improve this plot so that it look more aesthetic ?

Secondly, the resulotion of plot is not so good, and when I export this plot as jpeg file, quality of resolution deteriotate even more, I mean pixel tear out on zooming the image. How I fix this issue which I guess might be due to wrong way of exporting plot ?

i work on Maple 18 and recently maple standard worksheet interface not run properly.

i already have  uninstall and again i have same problems

Dear friends!

Please, suggest me, how to build a plot loocking as the following

plot

where the values on the axis X (1, 5, 10, 50, ...) are categories, not numbers?

if i install maple 2015 in amazon cloud, activate with my license

and i do not use amazon after several trial, 

will the license be used and can not activate in future if i use amazon cloud again in future?

any command or configure needed when using large amount memory such as 100GB memory?

 

 

Hi there,
I have a simple task to do with arrays. I have an 8x3000 array, whose columns are sometimes all zeroes (if any element in the column is zero then the entire column is zero). I want to eliminate the zero vectors, so I have this loop (the array is A)

for i from 1 to 3000 do
    while A(1,i)=0 do
        A:=DeleteColumn(A,i);
    end do;
end do:

Setting "A:=DeleteColumn(A,i);" reduces the size of the array, so if all the zero columns have been deleted at "i=200", Maple will keep trying to check the next column, which doesn't exist anymore. This gives an "index out of bounds" error, but also records "A" as the new smaller array, which is fine.

If I run this loop inside a procedure, the error stops the procedure, but it doesn't record the new array, it stays as the older, larger one. Does anyone know of a way around this?

Any help would be much appreciated.

Below and above the iterators, there is a graphic with numbers rotated in all directions.  I am thinking it is based somewhat on what I have done here http://www.mapleprimes.com/posts/97195-Wordle-In-Maple

How did they get the rotations in Maple?
