hard📝 Conceptual Q10 of 15
MATLAB - Cell Arrays and Structures
Which statement about MATLAB structures is TRUE?
AFields can be dynamically added by assignment using dot notation.
BStructure fields must be defined only at creation and cannot be changed.
CYou must use parentheses to access structure fields.
DStructure arrays can have different fields in each element.
Step-by-Step Solution
Solution:

  1. Step 1: Recall MATLAB structure flexibility

    MATLAB allows adding new fields anytime by assigning with dot notation.

  2. Step 2: Evaluate each statement

    A is false because structure arrays must have the same fields in each element. B is false because fields can be added later. C is false because dot notation is used, not parentheses. D is true.

  3. Final Answer:

    Fields can be dynamically added by assignment using dot notation. -> Option A

  4. Quick Check:

    Dynamic field addition is allowed = D [OK]
Quick Trick: Add fields anytime with dot notation assignment [OK]
Common Mistakes:
  • Thinking fields are fixed after creation
  • Using parentheses for field access
  • Assuming structure arrays can have different fields
