What does the MATLAB function det(A) compute when A is a square matrix?

AThe determinant of matrix A

BThe transpose of matrix A

CThe inverse of matrix A

DThe sum of all elements in matrix A

Step-by-Step Solution

Solution:

Step 1: Understand the function purpose
The function det(A) in MATLAB calculates a single number called the determinant for a square matrix A.
Step 2: Recall determinant meaning
