This is a high level post about algorithms (especially mathematical, scientific, and data analysis algorithms) which I hope can help people who are not researchers or numerical software developers better understand how to choose and evaluate algorithms.

    The C = C − A × B T micro-kernel is also a building block for Level 3 BLAS routines other than GEMM, e.g., symmetric rank k update (SYRK). Specifically, implementation of the Cholesky factorization for the CELL processor, based on this micro-kernel coded in C, has been reported by the authors of this publication [24]. 50% scientists expect IEEE Access Impact Factor will be in the range of ~ Impact Factor Trend Prediction System provides an open, transparent, and straightforward platform to help academic researchers Predict future journal impact and performance through the wisdom of crowds.
