Seldom to ask question after retired math hobby Just waiting for beauty who born in 1994 And waited for her email to mavio@protonmail.com What is the difference in ownership among different universe?

## @vv  I have network security conce...

I have network security concern to not to use mobile carrier network

how about the next two questions?

start from a^2 , result different from book photo?

how to calculate the orbit result at orbit size 3 at bottom table of the book photo?

## @vv  sorry for missing one photo ...

sorry for missing one photo

my notebook load maple prime web very slow, I can only use iphone

start from a^2 , result different from book above photo

and aa0 can not be calculated with orbit , and how to calculate the orbit result at orbit size 3 at bottom table of the book photo

## @vv  i understand now a^4 repeate...

i understand now

a^4 repeated for a^2

so not choose a^4

and if calculate larger than orbit size

it will repeated too

but I do not understand , start from a^2

the result is different from the book

and aa0 , can not calculate with orbit

return error

moreover when aa[3]= a^3

but how calculate the result having 3 numbers 036, 147 etc at orbit size 3

## @vv why orbit size 1 is 678how to c...

why orbit size 1 is 678

how to calculate this?

a^6 = a^0

how to calculate (018) .. etc at the bottom table

i use fixpoints and orbit function not work

and why it choose orbit size 1,2,3,6 only?

## @Kitonum  but i need a while to do...

but i need a while to do a further combination

from this result I need to choose 51 different rows

and search

## @tomleslie  I need 1 and 0 in all ...

I need 1 and 0 in all combination as described above

i expect larger , 10 one and 75 zero

## @Mariusz Iwaniuk my application is ...

my application is quantum matrix

one of invariant value sometimes is not exactly 1.0

i am thinking why invariant is not always invariant.

i searched that is caused by superposition

but convolution of list and sum result is the same as distributive law

so, how to use convolution to make invariant always invariant?

## @Mariusz Iwaniuk  restart:conv...

restart:
conv := proc(a, b)
c := []:
for k from 1 to nops(a)+nops(b)-1 do
result := 0:
for i from 1 to k do
if k-i+1 <= nops(b) and i <= nops(a) then
result := result + a[i]*b[k-i+1]:
end if:
od:
c := [op(c), result]:
od:
return c:
end proc:
with(LinearAlgebra):
M := Matrix([[1,2,3],[4,5,6],[7,8,9]]):
X := Matrix([[x1],[x2],[x3]]);
MatrixMatrixMultiply(M,X);
something should be convsolve(conv(M, X) = a value);
row1 := conv([seq(M[1][a],a=1..nops(M[1]))], [seq(Transpose(X)[1][a],a=1..nops(Transpose(X)))]):
sum(row1[mm], mm=1..nops(row1));
row2 := conv([seq(M[2][a],a=1..nops(M[2]))], [seq(Transpose(X)[1][a],a=1..nops(Transpose(X)))]);
sum(row2[mm], mm=1..nops(row2));
row3 := conv([seq(M[3][a],a=1..nops(M[3]))], [seq(Transpose(X)[1][a],a=1..nops(Transpose(X)))]);
sum(row3[mm], mm=1..nops(row3));
solve([sum(row1[mm], mm=1..nops(row1)), sum(row2[mm], mm=1..nops(row2)), sum(row3[mm], mm=1..nops(row3))], [x1,x2,x3]);

i do not know the definition of convolution of matrix with x to form a system of equations
i guessed shown above
if above is correct, then does it mean that solve can also solve this system?

how to replace distributive rules with convolution in maple?
if this can not be done, can i do it when only not use bracket ( ) to do multiply?

is there any example to show only convolution is correct when distributive is wrong?

## @tomleslie  is there any one know ...

is there any one know maple 12 use which method to expand the size of display graph?

## @tomleslie  what is yr ?is the...

what is yr ?

is there an simple example using dualaxisplot

vertical line is only x=1, x=2, x=3 etc for example around 12 lines

because i collect these lines with

L := [op(L), 1]

L := [op(L), 2]

etc

## @acer after tried today, it work in...

firstly I enabled maple security, then =0 not work then I disable security, it work but can not changed yesterday

after tried today, it work in window maple

i just curious why this command is applied globally but not session applied and it has affected after closed and open again

then I try again window discover =2 , display %1 = imaginary value before display matrix

then set =3 to solve this issue in maple

I use =0 mainly for copying many matrix in window

because =2 or =3 can not copy matrix

## @stefanv  but i really find invari...

but i really find invariant in 4x4

why is it pointless in more dimension?

there is no papers mention how to construct a general invariant matrix

and there is not only one kind of matrix invariant. Is there book teaching different kind of general module to find numerical invariant matrix?

## @mmcdara  i do not know the formul...

i do not know the formula

is there example code to show what happen?

If cube is not matrix

why do people solve cube game?

## @Carl Love not physics this time,&n...

not physics this time,

i am calculating combination of matrix 9 x 9 with 9 different elements, enumration to run all combinations

and also would like to know how the limit of maple , which size of matrix is the limit , such as 23^(23^2) combinations etc....

recently i write a function suitable for parallel computing, if one day run in amazon, how to massive install maple in amazon automatically and run script

is it manually copy script to 100 machines, and how to distributed computing this situation?

some people may guess 7 x 7 is the limit in x64 computer, but i do not believe, and would like to try

and also want to know whether there is technique to guess which range of combinations that have what i want to find, so that no need to run all

i just run , start from 30^(30^2) has zero ending

i guess limit is 29^(29^2)

## @Carl Love  is Schdinger equation ...

is Schdinger equation correct?

I/h is a very big number

and

where is Planck h coming from?

It seems can not Ket which show error
