Revised Direct Batch Evaluation of optimal orthonormal eigenvectors of the DFT matrix

A Revised and more numerically accurate version of the Direct Batch Evaluation by constrained Optimization Algorithm (RDBEOA) of orthonormal eigenvectors of the DFT matrix F is (RDBEOA) of orthonormal eigenvectors of the DFT matrix F is from the fact that it performs the singular value decomposition (SVD) of a matrix whose elements have almost half the range of values of the elements of the matrix to which the SVD is applied in the previous Direct Batch Evaluation by constrained Optimization Algorithm (DBEOA). Having more accurate Hermite-Gaussian-like (HGL) orthonormal eigenvectors of matrix F is a main requirement in the development of the discrete fractional Fourier transform (DFRFT).
