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 = min(exampleArray, [], 2);

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

Answer 1

The MATLAB command 'x = min(exampleArray, [], 2)' finds the minimum value of each row in the 'exampleArray'. Given the exampleArray, the result is [4; 6; -4], which corresponds to option A.

Step-by-step explanation:

The MATLAB command x = min(exampleArray, [], 2) calculates the minimum value of each row in the exampleArray. The second argument, [], means that no dimension is specified for the operation, and the third argument, 2, tells MATLAB to perform the operation across rows.

Given the exampleArray = [4, 6, 10; 11, 7, 6; 0, -1, -4], the minimum values across each row are 4, 6, and -4, respectively. Therefore, the output array x will be column vector with these minimum values.

The correct option from the given choices is A) [4; 6; -4].
