MATLAB: Problem using counter in a for loop

counterfor loops

I'm doing some practice problems for experience and can't get past an error with my counter with this function. What am I missing here?
Thanks in advance
function x = triangle(n)
i = 1;
for i:n-1
 x(i) = i+x(i+1); 
 i = i+1
end
end

Best Answer

There are at least two issues with this code:
function x = triangle(n)
i = 1;
for i:n-1
 x(i) = i+x(i+1); % (1) BOTH X(i) and X(i+1) ARE UNKNOWN, SO IT ERRORS
 i = i+1 % (2) THIS HAS NO EFFECT
end
end
As for issue 2, try this (first think would you think will be displayed ...)
for i=1:10 ; 
  disp(i)
  i = i + 7 ;
  disp (i)
end
