Question

Suppose the MATLAB variable exampleArray is defined by:

exampleArray = [4, 6, 10; 11, 7, 6; 0, -1, -4];
Which of the following arrays shows the results of the MATLAB command:

x = max(exampleArray, 2);
Options:

A) [10, 11, 2]
B) [4, 11, 0]
C) [11, 7, -1]
D) [6, 11, -1]

Answer 1

The MATLAB command x = max(exampleArray, 2); for the given matrix will output [10, 11, 0] as it calculates the maximum value in each row, making Option B) [10, 11, 0] the correct answer.

Step-by-step explanation:

In MATLAB, when the max function is applied to a matrix with the second argument as 2, it computes the maximum value in each row. For the given exampleArray, which is exampleArray = [4, 6, 10; 11, 7, 6; 0, -1, -4], the command x = max(exampleArray, 2) will result in an array where each element is the maximum value from the corresponding row of the exampleArray.

Therefore, the resulting array would be:

• Row 1 Maximum: 10
• Row 2 Maximum: 11
• Row 3 Maximum: 0

So, the correct MATLAB command result is:

x = [10, 11, 0];

Hence, the correct array from the given options is Option B) [10, 11, 0].
