MATLAB - Numerical Methods

Identify the error in this MATLAB code snippet that tries to compute the square root of each element in vector A:

A = [4, 9, 16, 25];
B = sqrt A;

Asqrt function requires two arguments

BUsing square root on a vector is not allowed

CVector A should be a column vector

DMissing parentheses around A in sqrt function

Step-by-Step Solution

Solution:

Step 1: Check MATLAB function syntax
Functions require parentheses around their arguments, so sqrt A is invalid syntax.
Step 2: Correct the syntax
Use sqrt(A) to compute element-wise square roots of vector A.
Final Answer:
Missing parentheses around A in sqrt function -> Option D
Quick Check:
Function calls need parentheses [OK]

Quick Trick: Always use parentheses for function arguments in MATLAB [OK]
