MATLAB - String Handling

You want to compare two cell arrays of strings c1 = {'cat', 'dog'} and c2 = {'Cat', 'dog'} ignoring case. Which MATLAB code correctly returns a logical array indicating matches?

Acellfun(@strcmpi, c1, c2)

Bstrcmpi(c1, c2)

Carrayfun(@strcmpi, c1, c2)

Dstrcmp(c1, c2)

Step-by-Step Solution

Solution:

Step 1: Understand cell array string comparison
strcmpi does not directly compare cell arrays element-wise.
Step 2: Use arrayfun with strcmpi for element-wise comparison
arrayfun(@strcmpi, c1, c2) applies strcmpi to each pair of elements, returning logical array.
Final Answer:
arrayfun(@strcmpi, c1, c2) -> Option C
Quick Check:
Use arrayfun with strcmpi for cell array comparison [OK]

Quick Trick: Use arrayfun(@strcmpi, c1, c2) for cell array string comparison [OK]

Common Mistakes:

Using cellfun instead of arrayfun
Calling strcmpi directly on cell arrays
Using strcmp instead of strcmpi
