What’s New in MATLAB R2020a and R2020b?

In this post I discuss new features in MATLAB R2020a and R2020b. As usual in this series, I focus on a few of the features most relevant to my work. See the release notes for a detailed list of the many changes in MATLAB and its toolboxes. Exportgraphics (R2020a) The exportgraphics function is very useful … Continue reading What’s New in MATLAB R2020a and R2020b?

What’s New in MATLAB R2019a and R2019b?

I didn’t have time earlier this year to write about the first MATLAB release of 2019, so in this post I will discuss R2019a and R2019b together. As usual in this series, I concentrate on the features most relevant to my work. Modified Akima Cubic Hermite Interpolation (R2019b) A new function makima computes a piecewise … Continue reading What’s New in MATLAB R2019a and R2019b?

What’s New in MATLAB R2018b?

The MATLAB R2018b release notes report a number of performance improvements, including faster startup and faster calls to built-in functions. I pick out here a few other highlights from the release (excluding the toolboxes) that are of interest from the numerical analysis point of view. The new xline and yline functions add vertical or horizontal … Continue reading What’s New in MATLAB R2018b?

What’s New in MATLAB R2017b?

Following my earlier posts What’s New in MATLAB R2016b? and What’s New in MATLAB R2017a? I take a look here at the R2017b release of MATLAB. As before, this is not a comprehensive treatment (for which see the Release Notes), but rather a brief description of the changes in MATLAB (not the toolboxes) that are … Continue reading What’s New in MATLAB R2017b?

What’s New in MATLAB R2017a?

MATLAB R2017a was released last week. Many of the changes reported in the release notes are evolutionary, building on and extending major new features introduced previously. For example, the Live Editor continues to gain expanded capabilities. In this post I pick out a few new features that caught my eye. This is very much a … Continue reading What’s New in MATLAB R2017a?

What’s New in MATLAB R2016b

MATLAB R2016b was released in the middle of September 2016. In this post I discuss some of its new features (I will not consider the toolboxes). This is personal selection of highlights; for a complete overview see the Release Notes. The features below are discussed in greater detail in the third edition of MATLAB Guide, … Continue reading What’s New in MATLAB R2016b

The Improved MATLAB Functions Expm and Logm

The matrix exponential is a ubiquitous matrix function, important both for theory and for practical computation. The matrix logarithm, an inverse to the exponential, is also increasingly used (see my earlier post, 400 Years of Logarithms). MATLAB R2015b introduced new versions of the expm and logm functions. The Release Notes say The algorithms for expm, … Continue reading The Improved MATLAB Functions Expm and Logm
