Please tell me how to calculate the derivative of a matrix function?

I am not interested in the mapleprime group, so I want to delete my account in this group.

Recently, my questions are deleted. last month I ask 3 questions but that all questions are deleted without my knowledge. yesterday also i ask one question "how to plot3d graph" that also deleted. "https://www.mapleprimes.com/questions/225618-How-To-Plot-The-3d-Graph?sq=225618". In the mapleprime, I am following the ethics and rules. 

Sorry, I comment not for answering question.

I want to ask a question, but I can't enter any 'Tags', but they need at least one tag.

There is not any text box where I can enter a tag.

Who can help me?

thanks!

I asked a question about importing a matrix with symbolic entries the other day.  Just got email saying there had been a reply.  But I can't find my question or that reply!  ............Edgar

If one looks in the profile of Rouben Rostamian , then one sees that any search in his Posts, Questions, Answers, and Replies is linked with MaplePrimes only. I informed  MaplePrimes staff about that disturbance without any effect. Using the opportunity, I'd like to pay attention of MaplePrimes users to many clones in the forum. This is a problem for ages: clones vote up themselves and impose one's opinion on  others. Several years ago some clones were deleted. It would be nice to continue that process.

I have a worksheet that illustrates a problem I have, How do I make this worksheet available on Mapleprimes?

Hi MaplePrimes Web managers

I suspect you have forgotten to update the lists for MapleSim "2017" you seem to stop at "MapleSim 2016", while I hear from your local office that MapleSim 2018 is "just around the corner" ...
It would make it easier to sort the issues for the last version, no ?

Thanks for your support
Sincerely
Ivar

Does MAPLEPrimes or MAPLESoft host a discussion forum on mathematics in general?  I know this site generally supports troubleshooting & code application.  I have had a couple of instances where I have posted a question that gets no responses because the question may fall outside the perview or objectives of troubleshooting & code application.  Perhaps I should pose these questions elsewhere?

The Maple Math button is not working for me in the MaplePrimes editor.  No matter what I enter as Maple Expression, I get You have entered an invalid Maple expression, no preview, and nothing is inserted.  The same goes for the Maple Plot button. 

I'm using Firefox 58.0.1 under Windows 10 (64 bit), but this also occurs with Internet Explorer.

   

I'm getting the message

Secure Connection Failed

when trying to get into this forum using the latest version of Firefox.
For writing this I used Internet Explorer.

The message continues with:

Has anybody else experienced the same?
What to do? 

There was a spam button that allowed a user with enough points to delete spam. It appears to have gone away, now we can just flag stuff as spam.

In LPSolve, I have solutions returned in matrix form that contain elements that are negligible (values close to zero).

Is there a simple way to convert and reduce these values to zero in the matrix (rather than return the exact values)?

 

Thanks!
