WebJul 17, 2024 · For this example RCOND is on the order of eps(1) and the scale factor for A2inv implies that its elements are useless. It's impossible to compute something that doesn't exist. A fairly recent addition to MATLAB is the function condest that estimates $\kappa(A)$ . Now condest(A) is preferable to 1/rcond(A). Inverse Webhilbert_conductor (a, b) # This is the product of all (finite) primes where the Hilbert symbol is -1. What is the same, this is the (reduced) discriminant of the quaternion algebra \((a,b)\) over a number field. INPUT: a, b – elements of the number field self. OUTPUT: squarefree ideal of the ring of integers of self. EXAMPLES:

WebApr 5, 2024 · To increase the space utilization, each unit cell is arranged in space according to the Hilbert fractal curve. Consequently, a metasurface absorber with 6 detuned unit cells is constructed. The multiple resonant cavities with dissimilar lengths can provide peak absorptions at multiple frequencies, thereby broadening the attenuation frequency range. The Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890. Because it is space-filling, its Hausdorff … See more Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well. This means that two data points which are close to each other … See more • Hilbert curve scheduling • Hilbert R-tree • Locality of reference • Locality-sensitive hashing • Moore curve See more • Warren Jr., Henry S.
