An identity matrix is a matrix with 1s in its principal diagonal and 0s in all the other places. Thus, its formula is In (or) I = [aij]n× n, where aij = 1 when i = j, and aij = 0 when i ≠ j. What is the Identity Matrix of order 3? In the identity matrix of order...
Finding a determinant of a square matrix The determinant is a scalar value that can be computed from the elements of a square matrix and encodes certain properties of the linear transformation described by the matrix. The determinant of a matrix A is denoted det, det A, or |A|. In SciPy...
