What New Functions or Features in R2023B are of Interest?

I was reading this question where Steve Lord suggested using a function expmv that is new in R2023B. I went over to the Matlab Release Notes and saw a few other things of interest (I should make a habit of checking the release notes!). Are there any new functions, features, etc. in R2023B (Matlab or toolboxes) that you think may be of interest to the community at large?

Please include link(s) to relevant doc page(s) if possible.

Answer 1

[Walter Roberson]

R2023b does not have many changes of interest to me.

What it does have that might be useful to me is,

Find and Replace Dialog Box: Use capture groups in regular expressions to search for and replace groups of characters

resize(): Resize data by adding or removing elements

Ordinary Differential Equations: Use object-oriented solution framework for ODEs

scatteredInterpolant Object: Use multivalued interpolation to interpolate multiple data sets simultaneously

Along with resize, there is now paddata and trimdata. I can see the latter two being useful on occasion.

New function svdappend sounds interesting. I wonder what typical use-cases might be? @Christine Tobler

[Bruno Luong]

Typical case is doing PCA when update with new data.

The update of various matrix desompositions has been discussed before. Personally I'm not fan and it doesn't promise advantage as the appareny attractiveness.
