strncmp(str_a, str_b, N) function basically takes 2 strings and a number N and
compares the 2 strings up to first N characters. If the first N characters are
equal in both strings, the function returns 1, otherwise 0.

Command - 


Output - 
error: strncmp: N must be greater than 0

In this example, MATLAB returns 1, which seems reasonable

Same unexpected error in case of the ignore-case version of this function -
