You don't need the "i=i+1" statement - the increment is contained next to the for statement;
for i = start:increment:end
disp(i);
i = i+1;
end
So for start = 1, increment = 1, end = 3 you would get "1 2 3" For start = 2, increment = 2, end = 7 you would get "2 4 6" Your added "i=i+1" affects everything after it, but then the value for i is re-written when the for loop begins again. For example, try this;
for i = 1:3
disp(i);
i = i+1;
disp(i)
end
Should give you the output; "1 2 2 3 3 4"
