From Wikipedia, Currying:

In mathematics and computer science, currying is the technique of converting a function that takes multiple arguments into a sequence of functions that each takes a single argument. For example, currying a function f that takes three arguments creates three functions:

becomes

or called in sequence: (note that this syntax is not supported in MATLAB (sadly!), though it is in GNU Octave)

Given f, a function handle, and n, the number of input arguments to later be passed into f, create a function handle g that is a curried form of f. Similar to the above example:

> curriedMax = currify(@max,3);

> curriedMax(magic(5)); ans([]); ans('all')

ans =

25

> curriedMax(magic(3))([])('all') %only works in Octave

Both of these are equivalent to

> max(magic(5),[],'all')
