strncmp

Compares at most $n$ characters of two character arrays in a case-sensitive manner.

Usage

strncmp(s1, s2, n)

• s1 and s2 should be arrays of characters.
• n should be a real integer, not equal to NaN.
• If n <= 0, it always returns true.
• If n is Inf, it compares max(numel(s1), numel(s2)) characters.
• It returns logical 1 if s1 and s2 are equal up to the n-th character.
• If s1 or s2 has less than n characters, it will be expanded to have n characters by packing trailing whitespaces.
• s1 and s2 are compared in a case-sensitive manner.
• Elements of s1 and s2 are indexed linearly.
• It returns logical 0 if s1 or s2 is not a character array.

Example

• The following inputs a and b have different sizes. strncmp compares their first n characters using linear indexing.

Input

a=['ace';'bdf']
b=['abcdex']
strncmp(a,b,5)
strncmp(a,b,6)

Output

a =
ace
bdf

b =
abcdex

ans =
1

ans =
0
