**A Distributed-Memory Package for Dense Hierarchically Semi-Separable Matrix Computations Using Randomization**

François-Henry Rouet, Xiaoye S. Li, Pieter Ghysels, Artem Napov

Article No.: 27

DOI: 10.1145/2930660

We present a distributed-memory library for computations with dense structured matrices. A matrix is considered structured if its off-diagonal blocks can be approximated by a rank-deficient matrix with low numerical rank. Here, we use...

**An Experimental Exploration of Marsaglia's xorshift Generators, Scrambled**

Sebastiano Vigna

Article No.: 30

DOI: 10.1145/2845077

Marsaglia proposed xorshift generators are a class of very fast, good-quality pseudorandom number generators. Subsequent analysis by Panneton and L'Ecuyer has lowered the expectations raised by Marsaglia's article, showing several weaknesses of...

**Manycore Algorithms for Batch Scalar and Block Tridiagonal Solvers**

Endre László, Mike Giles, Jeremy Appleyard

Article No.: 31

DOI: 10.1145/2830568

Engineering, scientific, and financial applications often require the simultaneous solution of a large number of independent tridiagonal systems of equations with varying coefficients. Since the number of systems is large enough to offer...

**Discrete Wavelet Transforms in the Large Time-Frequency Analysis Toolbox for MATLAB/GNU Octave**

ZdenĚK Průša, Peter L. Søndergaard, Pavel Rajmic

Article No.: 32

DOI: 10.1145/2839298

The discrete wavelet transform module is a recent addition to the Large Time-Frequency Analysis Toolbox (LTFAT). It provides implementations of various generalizations of Mallat's well-known algorithm (iterated filterbank) such that completely...

**Algorithm 963**: Estimation of Stochastic Covariance Models using a Continuum of Moment Conditions

Marcos Escobar, Benedikt Rudolph, Rudi Zagst

Article No.: 33

DOI: 10.1145/2834115

We describe the implementation of a parameter estimation method suitable for models commonly used in quantitative finance. The Continuum-Generalized Method of Moments (CGMM) is a Generalized Method of Moments (GMM) type of methodology that applies...

**Algorithm 964**: An Efficient Algorithm to Compute the Genus of Discrete Surfaces and Applications to Turbulent Flows

Adrián Lozano-Durán, Guillem Borrell

Article No.: 34

DOI: 10.1145/2845076

A simple and efficient algorithm to numerically compute the genus of surfaces of three-dimensional objects using the Euler characteristic formula is presented. The algorithm applies to objects obtained by thresholding a scalar field in a...
