Hi, i'm trying to change Matrix([[9,8,7],[6,5,4],[3,2,1]]) into Matrix([[1,2,3],[4,5,6],[7,8,9]]). I try to use FlipDimension, it works with two steps, but i cant seem to fit it into one step. Is there a simplier thing that i could do please? Thanks.

Hi,

i've been using evalf(Pi*5.6) for my calculations. after a few steps of calculations, some of the values are as small as 7.4x10^-9 . These small values are insignificant to my calculations. how should i ask maple to ignore all the positive and negative values that are smaller than 1x10^-9?

Please advice. Thanks

Hi, I have two matrix

a:=Matrix([[4,3,4],[7,7,3],[7,3,1]]):

b:=Matrix([[6,3,5],[9,8,0],[8,8,1])):

How do i make it into a [9x9] matrix? I is a diagonal matrix in the sequence of a,b,b,a. The first end of first "a" is added with begining of "b", the end of second "b" is added with the begining of third "b", and the end of third "b" is added with the beginning of final "a".

The answer that i'm getting shall be as follow :

c:=Matrix([[4,3,4,0,0,0,0,0,0...

Hi,

I am trying to proof that the right hand side is equal to the left hand side. When i do step by step, it clearly shows that my "c" and "d" are exactly the same thing. But when i use "evalb" and "verify", it comes out with "false". May I kwow what went wrong please?

Thanks.

Hi, I have a 4x4 matrix

How can I arrange it diagonally and make it into 3 repleating matrix? I'll get a 12x12 matrix, with the middle representation having negative values?

For example,

A:=Matrix([[2,2,8,5],[6,3,4,9],[5,5,7,4],[2,1,3,2]]);

I am trying to get something like B:=DiagonalMatrix(A,-A,A);

May I know what is the correct way of doing it please? Thanks.
