MATLAB - String Handling

You want to compare two cell arrays of strings C1 = {'Apple', 'Banana', 'Cherry'} and C2 = {'apple', 'banana', 'cherry'} ignoring case. Which MATLAB code correctly returns a logical array indicating matches?

Acellfun(@strcmpi, C1, C2)

Bstrcmpi(C1{:}, C2{:})

Ccellfun(@strcmp, C1, C2)

Dstrcmp(C1, C2)

Step-by-Step Solution

Solution:

Step 1: Understand cell array string comparison
To compare each pair of strings in cell arrays element-wise, use cellfun with a comparison function.
Step 2: Choose case-insensitive comparison
strcmpi ignores case, so cellfun(@strcmpi, C1, C2) applies it element-wise correctly.
Step 3: Why other options fail
cellfun(@strcmp, C1, C2) uses case-sensitive strcmp. strcmpi(C1{:}, C2{:}) unpacks cells into multiple arguments, causing a "too many input arguments" error. strcmp(C1, C2) is case-sensitive.
Final Answer:
cellfun(@strcmpi, C1, C2) -> Option A
Quick Check:
Use cellfun with strcmpi for cell array case-insensitive comparison [OK]

Quick Trick: Use cellfun(@strcmpi, C1, C2) for cell array case-insensitive compare [OK]

Common Mistakes:

Using strcmp instead of strcmpi for ignoring case
Unpacking cell arrays with strcmpi(C1{:}, C2{:})
Not using cellfun for element-wise comparison
