strncmpi

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

Usage

strncmpi(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-insensitive 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. strncmpi compares their first n characters using linear indexing.

Input

a=['Ace';'Bdf']
b=['abcdex']
strncmpi(a,b,5)
strncmpi(a,b,6)

Output

a = 
Ace
Bdf

b = 
abcdex

ans = 
1

ans = 
0
