- 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:
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
