MATLAB - Cell Arrays and Structures

c = {1, 2, 3};
c{4} = 4;
disp(c);

AError: Index exceeds matrix dimensions.

B{1, 2, 3, 4}

C{[1], [2], [3], [4]}

D{[1], [2], [3]}

Step-by-Step Solution

Solution:

Step 1: Understand cell array dynamic expansion
Assigning to c{4} adds a new cell element at position 4.
Step 2: Check the displayed cell array
The cell array now has four elements: 1, 2, 3, and 4.
Final Answer:
{1, 2, 3, 4} -> Option B
Quick Check:
Cell arrays expand dynamically when indexed beyond size [OK]

Quick Trick: Cell arrays grow automatically when assigning new indices [OK]
