Typing follwoing lines in MATLAB command line will output:a=23.3486; fprintf('a=   %5.2f ',a);Group of answer choices23.3523.423.3482.335

To answer the multiple-choice question about the output of the MATLAB command line statements, let's analyze the code provided.

1. Breakdown of the Problem

• The main command to evaluate is fprintf('a= %5.2f ',a); where a=23.3486. This command is used for formatted output.

2. Relevant Concepts

• The format specifier %5.2f in fprintf means:
  • % indicates the start of the format specifier.
  • 5 is the minimum field width (total number of characters to be printed, including the decimal point).
  • .2 indicates that two digits should be printed after the decimal point.
  • f indicates that the number is a floating-point number.

3. Analysis and Detail

• The value of a is 23.3486.
• When formatted with %.2f, MATLAB will round the number to two decimal places.
• Thus, rounding 23.3486 to two decimal places gives 23.35.

4. Verify and Summarize

• Check against the choices provided:
  • 23.35 (this matches the rounded output).
  • Other choices: 23.42, 23.348, and 2.335 do not match the expected output.

Final Answer

The output of the MATLAB command will be: 23.35.
