strcmp

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')
