Hi, I've written some matrix computation in maple 18 . I wanna open this file in maple 16 ? how is it possible ? any help is appreciated in advance.

When I open my file I got an error message says "there were problems during loading process"

and some of my text are missing.

Can anyone help me,please

how to access the variable which is currently running in another worksheet

to use for loop to read the Table

when worksheet is evaluating for a very long time, 

expect to read the value Table T in anther worksheet

 

worksheet1

for i from 1 to nops(polylistresult) do

if i < j then
for j from 1 to nops(polylistresult) do
for k from 1 to nops(polylistresult) do

if j < k then

with(Groebner):
F := [polylistresult[i], polylistresult[j], polylistresult[k]];
h := function1(F, {x, y, z}, s);
T[h] := [op(T[h]), F];

end if:

worksheet2 :

for i in indices(T) do
oo:=i[1];

Dear all

I want your help in a problem.I want to substitute in a summarization ,the variables for Vi and ξi.Because the number of variables are more than 200 I want to know if there is a way to take them from the excel sheet and put the to my program.attached are the maple worksheet and the variables table

P.s. i have done it for 44 variables

Attached is my sheet.

On my system if just execute the whole worksheet maple return the last statement's integral un evaluated, however at this point if re-execute the statements from the definition of L2, it looks that maple has evaluated the last statement's integral.

 

What am I missing here, any help?

Regards!!

Phil Yasskin (Texas A&M) has prepared a maplet for the Maplets for Calculus proiect. While this maplet works, in Malmem 18 it sometimes does NOT display the plot. We don't see this behavior in Maple 17, The maplet is attached for your convenience, if you are interested in seeing if it works for you.

The problem is difficult to describe. Basically, at the end of the problem, users can elect to see a plot of the function with(some) asymptotes. The code creates the plot when the problem is created, and displays this plot in the worksheet. But, when the plot is requested within the mapmlet, it sometimes does not show in the empty plot window.

Any explanations (or followup quesitons) will be greatly appreciated.

Hi Maple friends.

I have a plot. I click on the plot, and the blue border appears the around the plot. I press the delete key on my keyboard, and the plot is not deleted. Not deleted when I press the backspace key either. I can right-click on the plot and choose 'cut', but that just copies the plot to the clipboard.

So how can I delete a plot from the worksheet, without deleting anything else?

Thanks in advance.

Is there a way to open a classic worksheet in macintosh, even running windows through a virtual machine?

Hi there

I'm working with maple 13 (2d input) and I would like to hide the input in a worksheet, as follows:

view > show/hide contents > (unchecking) input

however i want to insert comments as text that will remain in my worksheet. Using '#' doesn't help, coz they get hidden too.

Couldn't sort out how to do this, any tips?

cheers

My problem is i am working with a very large randomly generated output, generated using maple's builtin in random generating functions. I have the output which i want to investigate but i want to be able to reproduce this result when i save and close the worksheet. Since the list of generators is very long copy pasting is not very nice and i donot know the seed of these generaters. I want to ask if i can store the values in variable in the worksheet so that when i open the worksheet i can get the same random generates stored in the variable.

Work Sheet issue...

Using maple 16. When I run a worksheet it adds in extra rows of the red >s. The attached example was run 3 times. How do I stop this happening?

I don't know why it says : Error, (in f) unable to store '[0.]/(0.17571268341557e16+[-0.25659510610770e15])' when datatype=float[8]

I'm currently using maple for calculations of robot kinematics.

My problem is that if i run my worksheet twice  Maple stops showing my results and starts to show e.g. _rtable 18446744074374081822 instead. How can i avoid this behaviour?

(I have a restart command in the beginning of my worksheet)

 

EDIT'

It seems that the strange behaviour doesent always happen when i run the worksheet twice.

Sometimes i need to run it three times or sometimes i just have to wait for a period of time and run it again. Restarting maple (Closing and reopening the program) fixes the problem every time.

I dont change any parameters between runs.

Normal behaviour 

Strange behaviour
