MATLAB - String Handling

Given two string arrays A = ["one", "Two", "three"] and B = ["One", "two", "Three"], which MATLAB expression returns a logical array indicating case-insensitive equality?

AA == B

Bstrcmpi(A, B)

Cstrcmp(A, B)

Disequal(A, B)

Step-by-Step Solution

Solution:

Step 1: Understand string array comparison
strcmpi supports element-wise case-insensitive comparison of string arrays.
Step 2: Check other options
A == B compares with case sensitivity; strcmp is case-sensitive; isequal checks full equality including case.
Final Answer:
strcmpi(A, B) -> Option B
Quick Check:
Case-insensitive string array compare = strcmpi [OK]

Quick Trick: Use strcmpi for case-insensitive string array comparison [OK]

Common Mistakes:

Using == operator for strings
Confusing strcmp with strcmpi
Using isequal which is case-sensitive
