[Solved] Identify the error in this MATLAB code:X = 1:5; Y = 1:5; Z = X.^2 + Y.^2; mesh(X, Y, Z); — Ans: Z is not a matrix matching X and Y dimensions | MATLAB

MATLAB - 3D Plotting and Visualization

Identify the error in this MATLAB code:

X = 1:5; Y = 1:5; Z = X.^2 + Y.^2; mesh(X, Y, Z);

Amesh requires vectors, not matrices

BX and Y must be row vectors only

CZ is not a matrix matching X and Y dimensions

DMissing semicolon causes syntax error

Step-by-Step Solution

Solution:

Step 1: Check dimensions of X, Y, Z
X and Y are vectors, but Z is computed element-wise and results in a vector, not a matrix matching meshgrid output.
Step 2: mesh expects matrices from meshgrid
mesh requires X, Y, Z matrices of the same size, so Z must be computed after meshgrid.
Final Answer:
Z is not a matrix matching X and Y dimensions -> Option C
Quick Check:
mesh needs matching matrix sizes [OK]

Quick Trick: Use meshgrid before computing Z for mesh plots [OK]
