"Subscript indices must either be real positive integers or logicals."

That could happen if you accidentally defined a variable named "sqrt".
Another common problem is using "i" (lower-case I) as a subscript in a location where "i" has not been assigned a numeric value. "i" is pre-defined as sqrt(-1) so you do not get a message about "i" being undefined if you do that. "j" has exactly the same issue.
