how to create matrix?

node = 3;

i want this matrix logically

0 1 1

1 0 1

1 1 0

please help to generate this

Answer 1

[DGM]

Something like this?

node=3;
mymat=1-eye(node);

That was answered already a while ago. https://www.mathworks.com/matlabcentral/answers/774237-how-to-create-a-matrix-in-matlab#comment_1396507

Using a different implementation of generating these matrices will not solve the problem that you are trying to implement an algorithm from a paper that is incorrect and that the paper needs to be fixed.

i know that algarithm will be wrong. but i can try to solve any other ways

[ankanna]

node = 3;

NN = toeplitz(node+1:-1:2);

mask = logical(fliplr(diag(ones(1,node-1),-1)));

NN(mask) = 1;

please explain detail using this terms. i dont understand to this code. please explain any simple way to understand this code

Answer 2

[Robert Brown]

you can specify the elements of a 3x3 matrix as follows:

>> a = [1 2 3; 4 5 6; 7 8 9]

the result will be

a =

1 2 3

4 5 6

7 8 9

with the correct order of 1's and 0's, you should be able to build the arrays you wish to have...

I hope this helps :-)

[ankanna]

n = 3;

Link=(n*(n-1))/2;

c=2^Link;

NN = toeplitz(Link+1:-1:2)

mask = logical(fliplr(diag(ones(1,Link-1),-1)));

NN(mask) = 1;

for c = 0:2^Link-1

l = bitget(c, NN)

end

the above code i generate all configuration matrix.

i need to generate all paths in this network.

please help me to generate all paths in the network
