WebThe determinant can be viewed as a function whose input is a square matrix and whose output is a number. The simplest square matrix is a $1 \times 1$ matrix, which isn't very interesting since it contains just a single number. The determinant of a $1 \times 1$ matrix is that number itself. WebThis number is called the determinant of that square matrix. It can be thought of as a mapping function that associates a square matrix with a unique real or complex number. So, we can say that a square matrix A with order ‘n’ and the same number of rows and columns will have a single real or complex number that captures important ...
