Virtually all tomography today is computed tomography. Binomial coefficients can be computed explicitly in various ways. The distance formula 43 is usually computed using numerical optimization. In practice, eigenvalues of large matrices are not computed using the characteristic polynomial. Only the table entries corresponding to powers of two need to be computed directly. He also computed probabilistic estimates of the error. The Lagrange polynomial can also be computed in finite fields. The effect size can be computed the same as above, but using the probabilities instead. When is an integer, the gamma function can be computed explicitly. PageRank can be computed either iteratively or algebraically. The algorithm is simple enough that it can be computed mentally. The integral may be efficiently computed by Gaussian quadrature. Historically, flattening was computed from grade measurements. Arrays are useful mostly because the element indices can be computed at run time. These metrics are therefore computed statically from the code.
