MATLAB - Cell Arrays and Structures
What will be the output of this MATLAB code?
fields = {'a', 'b', 'c'};
for k = 1:3
S.(fields{k}) = k*10;
end
disp(S.b);What will be the output of this MATLAB code?
medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Loop assigns values to fields a,b,c
k=1: S.a=10; k=2: S.b=20; k=3: S.c=30;Step 2: Display S.b value
disp(S.b) prints 20.Final Answer:
20 -> Option AQuick Check:
Loop dynamic fields = S.b = 20 [OK]
Quick Trick: Use curly braces to access cell array elements [OK]
Common Mistakes:
- Using parentheses instead of curly braces for cell access
- Confusing field names with loop index
- Expecting error due to dynamic fields
