In mathematics, for a given complex Hermitian matrix M and nonzero vector x, the Rayleigh quotient (,), is defined as:: p. 234 (,):=.For real matrices and vectors, the condition of being Hermitian reduces to that of being symmetric, and the conjugate transpose to the usual transpose .Note that (,) = (,) for any non-zero real scalar .Also, recall that a Hermitian (or real symmetric) matrix … of 3 * 3 matrix First . For a 2 x 2 matrix the minor of each position M[r,c] is the … b) Form Cofactor matrix from the minors calculated. . To calculate adjoint of matrix we have to follow the procedure a) Calculate Minor for each element of the matrix. Data Types: double. In other words, we can say that matrix A is another matrix formed by replacing each element of the current matrix by its corresponding cofactor and then taking the transpose of the new matrix … I find matrix of cofactor. The matrix conjugate transpose (just the trans-pose when working with reals) is also called the matrix adjoint, and for this reason, the vector is called the vector of adjoint variables and the linear equation (2) is called the adjoint equation.
