I scrolled across the image - jie is already defined as a struct (possibly in the code before this particular lines), thus you can not over-write it using indexing.

You can either

1) Over-write jie completely, like this -

jie = [limit(f, inf) limit(f, +inf) limit(f,-inf)]

or

2) Clear jie and then assign the limit values -

clear jie
jie(1) = limit(f, inf)
jie(2) = limit(f, +inf)
jie(3) = limit(f, -inf)
