Dear Maple users

I have done some experiments with the new Workbook feature in Maple 2016. It is a very welcome addition, indeed. Earlier I have created Maple files in which data from an external Excel file was imported and being used for certain calculations. In order to make recalculations work properly, one need to let the Excel file follow the Maple file. That's where a Workbook come in handy! I tried placing those two files in a Workbook. It didn't work completely as advertised, I think. I moved the Workbook to another location on the harddrive to make sure it wouldn't interfere with the original files outside the Workbook. Then I recalculated the Maple document inside the Workbook. The good thing: The data from the Excel file was still present. The bad thing: If I changed some data in the Excel file inside the Workbook, it didn't register in the Maple file when updating it!

Maybe I should explain that I did import data from the Excel file into Maple via the menu: Tools > Assistants > Import Data... The data was retrieved as a matrix within the Maple file and assigned to a variable and used for plots ...

Why doesn't the above procedure work properly? I hope one don't need to use the Workbook URI to reference files within the workbook. It is not that userfriendly!

I was born on the fourth day of december in 1982 and in next 19 days i am the member of

mapleprimes for exactly 4 years ...

i read about the history of maple , so i noticed it is as old as me :) lucky fo me !

then i interested to know whether is there any special event in the maple lifesplan on my birth day ?

Hello,

I am trying to force Maple to read big matrices from files, produced by other programs (GAP in my case).

 

The output looks like this after it's been saved in a *.txt file:

[ [ 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0,

Hi

I want to find the optimum of

G*(.7500000000*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))-.7500000000*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))*a+.7500000000*a*sqrt(a^2/(a^2+B^2-2.*B^2*a+B^2*a^2)))

+

(1-G)*(-6.250000000*10^(-12)*sqrt(a^2/(a^2+B^2-2.*B^2*a+B^2*a^2))*(5.833333333*10^9*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))-7.500000000*10^9)*(4.*a-3.*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))+3.*B*sqrt((1.-2.*a+a^2...

I wonder what virtue there would be in an "assistant" in the Standard GUI to show and allow control of the interface settings.

In the absence of a built-in assistant (or tab in the Tools->Options panels) I wonder whether a simple Maplet would serve.
