strcmp
compare character strings
Syntax
res = strcmp(string_one, string_two) res = strcmp(string_one, string_two, "i")
Arguments
- string_one
a character string or matrix of character strings.
- string_two
a character string or matrix of character strings.
- 'i'
optional parameter to compare strings in a case-independent way. Default value is
's'
.- res
a matrix of integers.
Description
res = strcmp(string_one, string_two)
(or
res = strcmp(string_one, string_two, 's')
) returns an
integral value indicating the relationship between the strings.
The value greater than zero indicates that the first character that
does not match has a greater value in string_one
than in string_two
and the value less than zero
indicates the opposite (lexicographical order).
The value equal zero indicates that string_one
and string_two
are equal.
res = strcmp(string_one, string_two, 'i')
returns
0
if string_one
is equal to
string_two
(case independently) and
1
indicates the opposite.
Examples
TXT1 = ['scilab','SciLab';'Strcmp','STRcmp']; TXT2 = ['ScIlAb','sciLab';'sTrCmP','StrCMP']; strcmp(TXT1,TXT2) strcmp(TXT1,'scilab') strcmp(TXT1,'SciLab') strcmp(TXT1,TXT2,'i') strcmp(TXT1,TXT2,'s')
