This module re-exports the functionality in Sized
specialized to Vector
.
Functions returning a vector determine the size from the type context unless
they have a '
suffix in which case they take an explicit Proxy
argument.
Functions where the resultant vector size is not know until compile time are not exported.

Restricting memory usage
force :: Vector n a -> Vector n a Source #
O(n) Yield the argument but force it not to retain any extra memory, possibly by copying it.
This is especially useful when dealing with slices. For example:
force (slice 0 2 <huge vector>)
Here, the slice retains a reference to the huge vector. Forcing it creates a copy of just the elements that belong to the slice and allows the huge vector to be garbage collected.
Modifying vectors
Bulk updates
:: Vector m a | initial vector (of length |
-> [(Finite m, a)] | list of index/value pairs (of length |
-> Vector m a |
O(m+n) For each pair (i,a)
from the list, replace the vector
element at position i
by a
.

:: Vector m a | initial vector (of length |
-> Vector n (Int, a) | vector of index/value pairs (of length |
-> Vector m a |
O(m+n) For each pair (i,a)
from the vector of index/value pairs,
replace the vector element at position i
by a

This function is useful for instances of Vector
that cannot store pairs.
Otherwise, update
is probably more convenient.

from the index vector and the
corresponding value b
from the the value vector,
replace the element of the initial vector at
position i
by f a b
.
accumulate_ (+) <5,9,2> <2,1,0,1> <4,6,3,7> = <5+3, 9+6+7, 2+4>
This function is useful for instances of Vector
that cannot store pairs.
Otherwise, accumulate
is probably more convenient:
accumulate_ f as is bs =accumulate
f as (zip
is bs)
:: (a -> b -> a) | accumulating function |
-> Vector m a | initial vector (of length |
-> [(Int, b)] | list of index/value pairs (of length |
-> Vector m a |
Same as accum
but without bounds checking.
:: (a -> b -> a) | accumulating function |
-> Vector m a | initial vector (of length |
-> Vector n (Int, b) | vector of index/value pairs (of length |
-> Vector m a |
Same as accumulate
but without bounds checking.
:: (a -> b -> a) | accumulating function |
-> Vector m a | initial vector (of length |
-> Vector n Int | index vector (of length |
-> Vector n b | value vector (of length |
-> Vector m a |
Same as accumulate_
but without bounds checking.
Permutations
O(n) Yield the vector obtained by replacing each element i
of the
index vector by xs
. This is equivalent to !
i
but is
often much more efficient.map
(xs!
) is
backpermute <a,b,c,d> <0,3,2,3,1,0> = <a,d,c,d,b,a>
Same as backpermute
but without bounds checking.
