Very early on in this blog (2006!), I wrote a post on memoizing functions, i.e., caching results so outputs that have already been calculated don't need to be calculated again (code included at the... 続きを読む >>

You may have heard the phrase "no ifs, ands, or buts" - meaning that there whatever the issue is, there is a definitive, non-negotiable answer or outcome. I heard it often when trying to persuade my parents to allow me to do something they didn't want me to do. Today when I heard someone use that phrase, what I sort of heard instead was "no |Inf|s, |NaN|s, or bits". So I will talk about those values and types today.... 続きを読む >>

One of the reasons I like using anonymous functions is because they allow me to express whatever function I want to use as a function of the relevant arguments in different contexts.... 続きを読む >>

When you call a function in MATLAB, MATLAB first evaluates all the inputs, and then passes these (possibly) computed values as the inputs. Recently Ljubomir Josifovski asked if... 続きを読む >>

For a lot of calculations, it makes sense to combine operations into a single expression. You can sometimes do this easily when you have function handles and you generate one... 続きを読む >>
