Study Notes
Determinants
- A determinant is a number (real or complex) associated with a square matrix.
- The determinant of a matrix A is denoted by |A|, det A, or ∆.
- Each element in the matrix has an index, aij, representing the row (i) and column (j) position within the matrix.
- A determinant can be thought of as a function.
- This function maps each square matrix to a unique number.
- The determinant of a square matrix A is a number associated with matrix A.
- A determinant can be viewed as a function that associates each square matrix with a unique number (real or complex).
- If M is the set of all square matrices, K is the set of all numbers (real or complex), and f : M → K is a function defined by f(A) = k, where A ∈ M and k ∈ K, then f(A) is called the determinant of A.
