[Solved] Find the error in this MATLAB code:f = @(x) x^2;result = integral(f, 0, 1); — Ans: Function handle uses scalar operator ^ instead of element-wise .^ | MATLAB

MATLAB - Numerical Methods

Find the error in this MATLAB code:

f = @(x) x^2;
result = integral(f, 0, 1);

Aintegral requires vector inputs, not function handles

BFunction handle uses scalar operator ^ instead of element-wise .^

CLimits 0 and 1 are invalid for integral

DMissing semicolon after function handle

Step-by-Step Solution

Solution:

Step 1: Check function handle definition
Function handle uses x^2, which is scalar power; for vector inputs, use x.^2.
Step 2: Understand integral input
integral passes vector inputs to function handle, so element-wise operator is needed.
Final Answer:
Function handle uses scalar operator ^ instead of element-wise .^ -> Option B
Quick Check:
Use .^ in function handles for integral [OK]

Quick Trick: Use .^ for element-wise power in function handles [OK]
