@acer kind help with a regression plane for the data

@acer in my data as you see in above x and y doesn't take sequencial vslues

@tomleslie supposs i want X and Y as on axis and plot a 2D for

f(x, y) =72.7x-24.5y  say

How to plot x vs y

With f(x, y)

2D plot

@acer I have maple 2020 to you size

@tomleslie How to change the scale of the plot

So that plot looks bigger

@vs140580 I copied the file itself to download folder for now it worked

My download folder path is 

C:\Users\Sriram\Downloads 

can you help me correct the file command

@Joe Riel is it possible for download directory not to have write permission even though i can download files into it

How to make a directory to get write permissions kind help

Great answer excellent 

@Carl Love no I changed the phyton output to string as my input will not be accepted directly by maple 

@Carl Love Now if I have a string like

A:="[[0,1,0,0,0,0,0,0,0,0,0,0,0],[1,0,1,0,0,0,0,0,0,0,0,0,1],[0,1,0,1,0,0,0,0,0,0,0,0,0],[0,0,1,0,1,0,0,1,0,0,0,0,0],[0,0,0,1,0,1,0,0,0,0,0,0,0],[0,0,0,0,1,0,1,0,0,0,0,0,0],[0,0,0,0,0,1,0,1,1,0,0,0,0],[0,0,0,1,0,0,1,0,0,0,0,0,0],[0,0,0,0,0,0,1,0,0,1,1,1,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,1,0,0,0,0,0,0,0,0,0,0,0]]"

I want convert it to as a  matrix say

B:=[[0,1,0,0,0,0,0,0,0,0,0,0,0],[1,0,1,0,0,0,0,0,0,0,0,0,1],[0,1,0,1,0,0,0,0,0,0,0,0,0],[0,0,1,0,1,0,0,1,0,0,0,0,0],[0,0,0,1,0,1,0,0,0,0,0,0,0],[0,0,0,0,1,0,1,0,0,0,0,0,0],[0,0,0,0,0,1,0,1,1,0,0,0,0],[0,0,0,1,0,0,1,0,0,0,0,0,0],[0,0,0,0,0,0,1,0,0,1,1,1,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,0,0,0,0,0,0,0,1,0,0,0,0],[0,1,0,0,0,0,0,0,0,0,0,0,0]]

How to do this

This type of matrix is my input say

I want

A:=[[0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1], [0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0], [0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 1, 1, 0], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]

This type of matrix is my output

can you help sir

But this is in general

In the first set instead of , it is ". " and at the end of each ] no ], inside

DistE := proc(v, e, g::GRAPHLN)

local Adj;

Adj := AdjacencyMatrix(g);

if Distance(e[1], v) < Distance(e[2], v) then

return 1;

else return 0;

end if;

end proc;

G := PetersenGraph();

V := Vertices(G);

V := [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

E := Edges(G);

E := {{1, 2}, {1, 5}, {1, 6}, {2, 3}, {2, 9}, {3, 4}, {3, 7}, {4, 5}, {4, 10}, {5, 8}, {6, 7}, {6, 10}, {7, 8}, {8, 9}, {9, 10}} DrawGraph(G);

DistE(V[1], E[3], G);

Error, (in DistE) invalid input: GraphTheory:-Distance expects its 1st argument, G, to be of type GRAPHLN, but received 1

I am getting the above error kind help to correct it.
