Hi ,how would i make this function go diagonal?,any help would be great
n = input ('sequence_matrix_');
fibb=[1,3:n];
for i=3:n
fibb(i)=fibb(i-1)*3+(i)-2;
end
fibb

Just do this small change
n = input ('sequence_matrix_');
fibb=[1,3:n];
for i=3:n
fibb(i)=fibb(i-1)*3+(i)-2;
end
diag(fibb)

n = input ('sequence_matrix_');
fibb = diag([1,3:n]);
for i=3:n
fibb(i,i) = fibb(i-1,i-1)*3+(i)-2;
end
fibb
