Identify the error in this MATLAB plot command:
plot(x, y, 'r--x-o')
AColor code 'r' is incorrect
BMultiple markers specified, which is invalid
CLine style '--' cannot be combined with markers
DMissing semicolon at the end
Step-by-Step Solution
Solution:

  1. Step 1: Analyze the plot style string 'r--x-o'

    This string tries to specify two markers: 'x' and 'o', which is not allowed in MATLAB plot format.

    Only one marker can be specified along with one line style and one color. Multiple markers are invalid.

  3. Final Answer:

    Multiple markers specified, which is invalid -> Option B

  4. Quick Check:

    Only one marker allowed in plot style [OK]
Quick Trick: Use only one marker symbol in plot style string [OK]
Common Mistakes:
  • Adding multiple markers in one style string
  • Ignoring MATLAB plot style syntax rules
  • Thinking semicolon affects plot style
