Strings vs Char and array indices
显示 更早的评论
Why do I keep getting this error message?
Array indices must be positive integers or logical values.
Error in movies_by_country (line 3)
if strlength(movies(ii).countries) >= strlength(movies(ii-1).countries)

I guess in your code, the variable ii starts from 1 which try to read
strlength(movies(0).countries)
In MATLAB the array indexes start from 1, so it gives an error.
