part

extraction of strings

Calling Sequence

[strings_out] = part(strings_in, v)

Arguments

:strings_in, strings_out Matrix of character strings. : :v Integer row vector. :

Description

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) ).

Examples

// returns characters position 8 to 11
part("How to use ""part"" ?",8:11)

// returns characters position 2 to 4 for each element
// no characters replaced by ''
c = part(['a','abc','abcd'],2:4)

// returns character position 1 for each element and add characters position 4 to 7 of each element
c = part(['abcdefg','hijklmn','opqrstu'],[1,4:7]);

// returns character 4 for each element, add characters position 1 to 7 and add character position 4 for each element
c = part(['abcdefg','hijklmn','opqrstu'],[4,1:7,4]);

// returns character position 1,add again character position 1 and character position 2
c=part(['a','abc','abcd'],[1,1,2])

// a a a
part(['a','abc','abcd'],[1])

// aa aa aa
part(['a','abc','abcd'],[1,1])

// aa aab aab
part(['a','abc','abcd'],[1,1,2])
