Question

Permutations Write a function permutation that will receive a positive integer n as an input argument. The function will return a vector of size n, where the elements of the vector are the positive integers from 1 to n, in random order. Each number from 1 to n should appear only once. You are required to use the programming method (loops, conditional statements). You are NOT allowed to use the following built-in Matlab functions: perms, randperm, randsample. Here is an example of calling the function:

Explanation / Answer

Matlab Function:

function p=permutation(n)
p=zeros(n,1);
for i=1:n
p(i)=i;
end
for i=1:n*n
x=randi([1,n]);
y=randi([1,n]);
z=p(x);
p(x)=p(y);
p(y)=z;
end
