part — extraction of strings
[strings_out] = part(strings_in, v)
Let s[k]
stands for the k
character of string s
( or the white space character if
k >length(s)
).
part
returns strings_out
, a
matrix of character strings, such that strings_out(i,j)
is the string "s[v(1)]...s[v(n)]"
(
s=strings_in(i,j)
).
