WebTwo matrices A and B are similar if there is a matrix P with which they fulfill the following condition: Or equivalently: Actually, matrix P acts as a base change matrix. So what this equation means is that matrix A can be expressed in another base ( P ), which results in matrix B. This term can also be called similarity transformation or ... WebIn mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose —that is, the element in the i -th row and j -th column is equal to the complex conjugate of the element in the j -th row and i -th column, for all indices i and j : Hermitian matrices can be understood as the ...
