- Indexing
Yorick is good at manipulating elements in N-dimensional arrays conveniently with its powerful syntax.
- Range of indices
Several elements can be accessed all at once:
> x=; > x > x(3:6) > x(3:6:2) > x(6:3:-2)- Arbitrary elements
- Pseudo-index
Like "theading" in PDL (Perl Data Language) and "broadcasting" in Numpy (Numeric extension for Python), Yorick has a mechanism to do this:
> x= > x > y=,] > y ,] > y(-,) ,,],,,]] > x(-,) ,,] > x(,-) ] > x(,-)/y ,] > y=,] > x(,-)/y ,]- Rubber index
".." is a rubber-index to represent zero or more dimensions of the array.
> x=,] > x ,] > x(..,1) > x(1,..) > x(2,..,2) 5"*" is a kind of rubber-index to reshape a slice(sub-array) of array to a vector.
> x(*)- Tensor multiplication
Tensor multiplication is done as follows in Yorick:
P(,+,,)*Q(,,+)
means
> x=,] > x ,] > y=,,] > x(,+)*y(+,) ,,] > x(+,)*y(,+) ,]Read more about this topic: Yorick (programming Language)
Famous quotes containing the word features:
“These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
—Plato (c. 427–347 B.C.)
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
“It is a tribute to the peculiar horror of contemporary life that it makes the worst features of earlier times—the stupefaction of the masses, the obsessed and driven lives of the bourgeoisie—seem attractive by comparison.”
—Christopher Lasch (b. 1932)
