why i getting this error index exceed matrix dimensions

[Walter Roberson]

Unfortunately you did not show us the value locl(1) and you did not show us the code used to assign to locl(1) . All we can say is that whatever value locl(1) is, it is greater than 77.

sir，may be check loc1 is or not empty

[Walter Roberson]

I was morally convinced that there was an error message about the limit being 77, but when I look again I was mistaken. Your point that locl might be empty is a good one.
