SYNTAX
str = substr(s,i,j)
str = substr(s,i,j,length_or_index)
DESCRIPTION
str = substr(s,i,j) returns the extracted part of s with length j beggining from i; or an empty vector if j < i or .
str = substr(s,i,j,length_or_index) the argument j is treated as the index of the last position of the substring inside s if length_or_index is equal to 'index'.

EXAMPLES

Outputs the substring from the second index position with a length of 3 chars.

str = substr('12345',2,3)
str =
'234'

Outputs the substring from the second to the third index position.

str = substr('12345',2,3,'index')
str =
'23'

INPUT ARGUMENTS

s — Input string
character vector or string scalar
String to extract a substring.
Data Types: string

i — Initial index
positive integer number
Number of the initial index inside str.
Data Types: double | single | int64 | int32 | int16 | int8

j — Length / End index
positive real number
Length of the output string if i > 0 or number of the end index inside str if length_or_index == 'index'.
Data Types: double | single | int64 | int32 | int16 | int8

length_or_index — Length or index
'length' (default) | 'index'
A string that interprets the input j as length when it is equal to 'length'.
or as an index when it is equal to 'index'.
