Half Precision Arithmetic: fp16 Versus bfloat16
The 2008 revision of the IEEE Standard for FloatingPoint Arithmetic introduced a half precision 16bit floating point format, known as fp16, as a storage format. Various manufacturers have adopted fp16 for computation, using the obvious extension of the rules for … Continue reading
What’s New in MATLAB R2018b?
The MATLAB R2018b release notes report a number of performance improvements, including faster startup and faster calls to builtin functions. I pick out here a few other highlights from the release (excluding the toolboxes) that are of interest from the … Continue reading
Bohemian Matrices in Manchester
Bohemian matrices are families of matrices in which the entries are drawn from a fixed discrete set of small integers (or some other discrete set). The term is a contraction of BOunded HEight Matrix of Integers and was coined by … Continue reading
Conversations with Gil Strang
At JuliaCon 2018 in London, one of the keynote presentations was a conversation with Gil Strang led by Alan Edelman and Pontus Stenetorp. Gil is well known for his many books on linear algebra, applied mathematics and numerical analysis, as … Continue reading
Tricks and Tips in Numerical Computing
In a keynote talk at JuliaCon 2018 I described a variety of tricks, tips and techniques that I’ve found useful in my work in numerical computing. The first part of the talk was about two aspects of complex arithmetic: the … Continue reading
What’s New in MATLAB R2018a?
MATLAB R2018a was released in March 2018. With each biannual release I try to give a brief overview of the changes in MATLAB (not the toolboxes) that are of most interest to me. These are not comprehensive summaries of what’s … Continue reading
How to Program log z
While Fortran was the first highlevel programming language used for scientific computing, Algol 60 was the vehicle for publishing mathematical software in the early 1960s. Algol 60 had real arithmetic, but complex arithmetic had to be programmed by working with … Continue reading
