From a previous thread, out of curiosity, I tried to find _EnvMaxCosetsToddCoxeter.  I could not do it using the built in help.  Now if I type ?group,pres, I can get to the help page for that item, and there it mentions _EnvMaxCosetsToddCoxeter and if need be, this value can be increased, using standard assignment operators.  O.K.  But where is a document that has the complete list of environment variables that can be changed and the details associated with each of those environment variables.&nb

What is the best way to include Maple output in this forum.  What are the steps necessary.  I use to copy the output from  my worksheet and paste it as Maple code, and it would work.  I have not been able to do this any more.  I am missing something.  Is the format Filtered HTML or Worksheet HTML?

Greetings. I have a question regarding the use of the Matrix Browser. I was experimenting with the Transpose function, trying to mimic the Matlab linear algebraic transpose. For a row Vector A, defined as: A=[0 1 2 3 4 5 6 7 ...] in Matlab A' will give me a column vector. 0 1 2 3 4 5 6 7 In Maple, ver. 11.02, using the Classic interface: >restart:with(LinearAlgebra): >A:=Vector[row]([0,1,2,3,4,5,6,7]); A := RTABLE(150962204,VECTOR([0, 1, 2, 3, 4, 5, 6, 7]),Vector[row]) >Transpose(A); RTABLE(151848540,MATRIX([[0], [1], [2], [3], [4], [5], [6], [7]]),Vector[column])
The last comment on this thread Singular Planet needs to be removed. This is Spam and does not belong here. Just thought I would point it out because sometimes things like this get missed. Regards, Georgios Kokovidis
Greetings. As mentioned in earlier posts, I often find the answer given to a question regarding the use of the 'sum' command as: don't use 'sum', use 'add', and all will be fine. I agree, and I use the add command for adding numbers together. But, if all I am doing is adding numbers together, from a sequence and nothing else, why not use the 'sum' command. It seems to be orders of magnitude faster than the 'add' command if there are a large number of numbers(I have no metric for what large is as far as numbers go). As an example, I execute the code below and look at the results. > restart:
