Hellow matlab comunity.

I want to generate (20*20) matrix with unique values for each row and each column and the range of values in each cell must be between 0 and 19 using 2D chaotic map and with matalb code.

for example, if the size of matrix is 4*4 the output must be as below:

0 3 2 1

1 2 0 3

3 0 1 2

2 1 3 0

and i want this output is fixed for each run.

2D chaotic map generate random numbers and it is sensetive to intial parameters

How does it generate random numbers?

You still didn't answer - What is the logic behind this output? and is the output I mentioned acceptable or not?

在 MATLAB Online 中打开

Try this:

numbers = repmat(randperm(20)-1, 1, 20);
randomIndexes = randperm(numel(numbers));
finalMatrix = reshape(numbers(randomIndexes), 20, 20)

unless you mean a Latin Square
