easy📝 Syntax Q3 of 15
MATLAB - 3D Plotting and Visualization
Which of the following is the correct syntax to create a contour plot with 10 contour levels in MATLAB?
Acontour(X, Y, Z, 'NumLevels', 10)
Bcontour(X, Y, Z, levels=10)
Ccontour(X, Y, Z, 'Levels', 10)
Dcontour(X, Y, Z, 10)
Step-by-Step Solution
Solution:
  1. Step 1: Recall contour levels syntax

    In MATLAB, the fourth argument to contour specifies the number of contour levels directly as a number.
  2. Step 2: Identify invalid syntax

    Options A, B, and C use incorrect parameter names or assignment syntax not supported by contour.
  3. Final Answer:

    contour(X, Y, Z, 10) -> Option D
  4. Quick Check:

    Number of levels = 4th argument number [OK]
Quick Trick: Specify levels as 4th argument number [OK]
Common Mistakes:
  • Using named parameters incorrectly
  • Passing string instead of number for levels
  • Using assignment syntax inside function call
