I have two functions, how can i use one in another ? I need to use my matrix A from first function in second one
function A = createMatrix(n, a)
n = 7
a = [3 4 1 2 5 2 1]
A = zeros(n);
for i = 1:n
for j = 1:n
A(i,j) = a(mod(j-i,n)+1);
end
end
end
There second
function period = findPeriod(A)
n = size(A, 1);
[~, idx] = max(A, [], 2);
idx = idx - 1;
g = n;
for k = 1:length(idx)-1
i = idx(k);
j = idx(k+1);
d = abs(i-j);
g = gcd(g, d / gcd(g, d));
end
period = g;
end

Ran in:
n = 7;
a = [3 4 1 2 5 2 1];
A = createMatrix(n, a)
A = 7×7
3 4 1 2 5 2 1 1 3 4 1 2 5 2 2 1 3 4 1 2 5 5 2 1 3 4 1 2 2 5 2 1 3 4 1 1 2 5 2 1 3 4 4 1 2 5 2 1 3
period = findPeriod(A)
period = 1
function A = createMatrix(n, a)
A = zeros(n);
for i = 1:n
for j = 1:n
A(i,j) = a(mod(j-i,n)+1);
end
end
end
function period = findPeriod(A)
n = size(A, 1);
[~, idx] = max(A, [], 2);
idx = idx - 1;
g = n;
for k = 1:length(idx)-1
i = idx(k);
j = idx(k+1);
d = abs(i-j);
g = gcd(g, d / gcd(g, d));
end
period = g;
end

Are you sure you did exactly the same as what Torsten did in their answer?
