This question on the Mathematica.SE siteshows how to generalisePartitionfor ragged lists (i.e., those with sub-lists that are not all the same length). There are a number of different ways to do this, including usingPartitionitself, as well as various combinations ofNestWhileandPrepend. Joi...

Since we want to get daily data for calibration of (generalized) Lanchester law models we can simply extrapolate the weekly data with daily averages. We can also over-impose in some way the two images (or plots) in order to convince ourselves that we have a faithful enough interpolation. l...

Users who join and log on to the site have only to type in their ZIP codes to locate available providers in their area, including both agency and individual providers. Some of these sites have become very sophisticated: they provide screening services (criminal background checks and verification...

And although Wolfram Language isn’t intended as an interactive video editing system, we’ve made sure that it’s possible to do streamlined programmatic video editing in the language, and for example in Version 14.0 we’ve added things like transition effects in VideoJoin and ti...
