A hermitian matrix is a matrix which is equal to its complex transpose. asked Mar 17 '12 at 13:42. The complex conjugate transpose of a matrix interchanges the row and column index for each element, reflecting the elements across the main diagonal. In 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: = ¯ or in matrix form: = ¯. Tips. Use the MATLAB matrix exponentiation function expm. Rarely heard "complex transpose" or "hermitian transpose". Vote. The matrices used in the examples above are a bit small to see this so, for this example, generate a larger matrix. Hermitian is a property, not something that can be generated. No, if you do that then b will not be uniformly distributed; it will have a triangular distribution. 0. https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#answer_218799, https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#comment_360481, https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#comment_790639, https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#comment_1081738, https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#comment_1081798, https://de.mathworks.com/matlabcentral/answers/280172-how-can-i-generate-hermitian-of-a-matrix-in-matlab#answer_377326.
