[Solved] Identify the error in this MATLAB code for 3D plotting: x = -5:5; y = -5:5; z = x.^2 + y.^2; mesh(x,y,z); | MATLAB

MATLAB - 3D Plotting and Visualization

Identify the error in this MATLAB code for 3D plotting:

 x = -5:5;
 y = -5:5;
 z = x.^2 + y.^2;
 mesh(x,y,z);

AVectors x and y must be converted to grids before computing z

BThe operator .^ is incorrect for element-wise power

CUsing mesh instead of surf causes error

DNo error; code runs fine

Step-by-Step Solution

Solution:

Step 1: Check vector and matrix sizes
x and y are vectors, but z is computed element-wise without matching sizes for mesh.
Step 2: Identify need for meshgrid
To compute z over a grid, x and y must be converted to matrices using meshgrid before element-wise operations.
Final Answer:
Vectors x and y must be converted to grids before computing z -> Option A
Quick Check:
meshgrid needed for grid data = C [OK]

Quick Trick: Use meshgrid to create X,Y grids before Z calculation [OK]
