easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall MATLAB root-finding function
MATLAB uses the functionrootsto find zeros of a polynomial given its coefficients.Step 2: Check syntax correctness
The correct syntax isroots(p), wherepis the coefficient vector.Final Answer:
roots(p) -> Option BQuick Check:
roots function syntax = roots(p) [OK]
Quick Trick: Use roots() to find polynomial zeros in MATLAB [OK]
Common Mistakes:
- Using polyval instead of roots
- Trying non-existent functions like findroots
- Passing wrong arguments to roots
