Question

Suppose the MATLAB variable exampleArray is defined by:

exampleArray = [4, 6, 10; 11, 7, 6; 0, -1, -4];
Click on the array that shows the results of the MATLAB command:

x = max(exampleArray(:));
Options:

A) [11, 10, 6; 4, 7, 0; -1, 6, -4]

B) [11]

C) [11, 7, 10; 4, 6, 6; 0, -1, -4]

D) [-4, -1, 0; 6, 7, 11; 10, 6, 4]

Answer 1

The MATLAB command 'x = max(exampleArray(:));' finds the maximum value within the entire array, returning the maximum value as a scalar, which is 11. Therefore the correct answer is Option B) [11]. The other options are incorrect as they show either reordered elements or maxima along specific dimensions.

Step-by-step explanation:

The MATLAB variable exampleArray is defined as a matrix with the values:

[4, 6, 10;
11, 7, 6;
0, -1, -4]

When the MATLAB command x = max(exampleArray(:)); is executed, it finds the maximum value within the entire array (due to the use of the colon operator ':' that converts the matrix into a vector). Hence, it returns the maximum value as a scalar. The correct option that represents this operation is:

Option B) [11]

The other options given show either reordered elements or maxima along specific dimensions, which do not correspond to what the command performs.
