[Solved] Find the error in this MATLAB code:[X,Y] = meshgrid(-1:1, -1:1); Z = X.^2 + Y.^2; contour(X, Y, Z, 'LevelList', [1 2 3]); | MATLAB

MATLAB - 3D Plotting and Visualization

Find the error in this MATLAB code:

[X,Y] = meshgrid(-1:1, -1:1); Z = X.^2 + Y.^2; contour(X, Y, Z, 'LevelList', [1 2 3]);

AThe vectors for meshgrid are too small

B'LevelList' is not a valid property for contour function

CZ calculation uses incorrect element-wise operators

DNo error, code runs and plots correctly

Step-by-Step Solution

Solution:

Step 1: Check contour property names
MATLAB contour does not support 'LevelList' property. Levels are specified positionally, e.g., contour(X, Y, Z, [1 2 3]).
Step 2: Verify other parts
Meshgrid vectors and Z calculation are correct with element-wise operators.
Final Answer:
'LevelList' is not a valid property for contour function -> Option B
Quick Check:
Use correct property names for contour [OK]

Quick Trick: Check property names carefully for contour vs contourf [OK]
