MATLAB - 3D Plotting and Visualization

X = 0:2; Y = [1 3 5]; Z = [2 4 6]; plot3(X, Y, Z, 'r-');

AA 2D plot ignoring Z values

BA red 3D line connecting points (0,1,2), (1,3,4), (2,5,6)

CAn error due to mismatched vector lengths

DA blue 3D line connecting points (0,1,2), (1,3,4), (2,5,6)

Step-by-Step Solution

Solution:

Step 1: Check vector lengths
X, Y, and Z all have length 3, so they match and are valid inputs.
Step 2: Interpret plot3 command
plot3 plots a red solid line ('r-') connecting the 3D points defined by X, Y, Z.
Final Answer:
A red 3D line connecting points (0,1,2), (1,3,4), (2,5,6) -> Option B
Quick Check:
Matching lengths + 'r-' = red 3D line [OK]

Quick Trick: Check vector lengths before plotting [OK]
