[Solved] What is wrong with this MATLAB code snippet? x = [1 2 3]; y = [10 20]; interp1(x, y, 2) — Ans: Vectors x and y have different lengths causing an error. | MATLAB

MATLAB - Numerical Methods

What is wrong with this MATLAB code snippet?

x = [1 2 3];
y = [10 20];
interp1(x, y, 2)

AVectors x and y have different lengths causing an error.

BThe query point 2 is outside the range of x.

Cinterp1 requires y to be a matrix, not a vector.

DThe syntax of interp1 is incorrect.

Step-by-Step Solution

Solution:

Step 1: Check vector lengths
Vector x has length 3, y has length 2; they must be equal for interp1.
Step 2: Identify error cause
Different lengths cause MATLAB to throw an error when calling interp1.
Final Answer:
Vectors x and y have different lengths causing an error. -> Option A
Quick Check:
Equal vector lengths needed [OK]

Quick Trick: Check x and y lengths match before interp1 [OK]
