How to find the inverse of any square matrix, using elementary matrix operations. Includes sample problems that demonstrate the technique step-by-step.
Since in upper triangular matrix, all elements under the principal diagonal are zeros, the eigenvalues are nothing but the diagonal elements of the matrix. What are the Eigenvalues of a Unitary Matrix? A unitary matrix is a complex matrix such that its inverse is equal to its conjugate transpos...
