MaplePrimes Activity


These are replies submitted by Christopher2222

These wishlists are a good thing as Maplesoft looks at them seriously, a few suggestions from these wishlists have come to light.  I'd like to see more activity in future wishlists and I look forward to seeing what additional changes have been added to the newest maple.  The audio tools department has been greatly improved, it could be improved further with mp3 format support. 

 

@tomleslie thanks

@tomleslie I missed that, no need to be harsh.  Thanks for the replies I appreciate it.

@tomleslie the idea was for any stringed information to be grouped together and numerical information as a separate column.  But more importantly was the amount of spacing between the separations that determined a column ie any singly spaced information would be grouped into one column and any more than 1 would be grouped into another

It seems there is no differentiation, using ImportMatrix, whether there is 1 or 2 or 8 spaces.  Using delimiter=" ".  However using delimiter="     " with 5 spaces throws Maple an error, or any number of spaces other than 1 for that matter. 

Although ImportMatrix with different spacing won't work using the spacebar, as long as the data is tabbed which signifies a control character, delimter="\t" can be used to identify the tabs. 

@Rouben Rostamian  re:space violation, I didn't even realize this.  I'll have to check the file I used or if I just copied it wrong, in which case the ImportMatrix delimiter option should then work.

Thanks tomleslie and Rouben Rostamian for your inputs. 

I should have specified a board, I didn't realize there were so many different ones.  Specifically lets use a classic one my daughter and grandparents were playing on.

 

Fairly simple to observe how many moves it would take, with one die I found at least 3 ways to finish in 7 moves.  And with two die I've found 3 ways to finish in 5 moves.  With 3 dice one way 3 moves. 

@fereydoon_shekofte Do you prefer stack exchange over mapleprimes?  Why wouldn't you just come here?

A quick thought, no time to think right now - The number of characters in the book should be ones that speak and so after the quotes we could search for the key words (asked, said, cried, yelled, shouted, answered, roared, replied etc.. ) and capture the names following such key words into a set.

In the help files plot,options I did find this note I've copied below, so it seems the standard interface is adhering to classic interface rules.

axiscoordinates
  axiscoordinates=t
  The coordinate system used for display of the axes. The value t can be either polar or cartesian. By default, Cartesian axes are displayed. If t is polar, then radial and angular axes are generated. This option is used together with the coords=polar option.
Note: This option is only available in the Standard interface.  In the Classic interface, the coordinates are always Cartesian.

 

I always see bad things happen when porting occurs (let's not do that) information is always lost. 

Your point is well taken (re:diluting breadth and depth of information)  I much prefer mapleprimes, and unless the forum format for a new maple forum is outstanding (stack exchange is sub par in my opinion) then I'm only going to follow one source.  A Maple forum on Stack Exchange could very well survive but Mathematica has 10x the number of users and so it's not a wonder why there's a main one and one on Stack. 

My guess is the reason a Maple forum attempt on stack exchange failed before was because of lack of interest.  My main question is ... What is the driving force for a forum for Maple on Stack Exchange anyway? 

I prefer mapleprimes, but I may check it out once in a while.  IMHO the forum format at stack exchange is aweful (the current mapleprimes, as some people mentioned, appears to be modelled after stack exchange).  I believe this modelling change was due to the type of programming change that was made when new programmers took over mapleprimes.  I will add an example of my preffered forum format when I find it (the one I had in mind changed it's formatting as well).

***edit add*** not exactly but better, this forum format is ok in my opinion http://orbiter-forum.com/

@acer It would also work without the colon dash, so long as it's executed before the with(plots) command is executed. 

@acer thanks yes that's what I was looking for.

Is is possible to rename the changecoords outside the plots package to something else?

Building on Markiyan Hirnyk get the coordinates of the points.
