我有一个包含撇号的XML字符串。我将撇号替换为对应的撇号&将修改后的字符串解析为XElement。然而,XElement正在将‘变回’为撇号。如何强制XElement.Parse保留编码后的字符串? 浏览0提问于2011-10-30得票数 0 回答已采纳 1回答 单引号单引号 可能重复: p `seq` q = \inp -> [((v,w),inp''...
-- takes an element and a list of elements that can be sorted and inserts it into the last position where it's still less than or equal to the next element. insert 4 [3,5,1,2,8,2] insert 4 [1,3,4,4,1] -- genericLength, genericTake, genericDrop, genericSplitAt, genericIndex...
In fact using the list monad you write like if you consider only one element at a time and the computation is done non deterministically. To find the smallest number such that mandel x y > 0 we use a simple dichotomy:-- given f min max nbtest, -- considering -- - f is an ...
matrixIndex’ y (r:rs) = case elemIndex e r of Just x → Just (x,y) Nothing → matrixIndex’ (y+1) rs matrixIndex returns the (x,y) position in the matrix of the given element (or Nothing if it is not found). 1.2 Number Theory Functions ...
A NodeList is not an array, but behaves like an array: we can ask for its length and retrieve an element by index. It is not an array itself, so modelling it as such in Haskell would be incorrect. However, by allowing import entities to use Javascript array notation we circumvent this...
The shape of the array is there to tell Repa how to interpret the operations on it. For example, if we ask for the element at index Z:.2:.1 in an array with shape Z:.3:.5, we’ll get the element at position 2 * 5 + 1 in the vector. We can try it using the ! operator...
key combination to jump to the definition of an element when you are over it.Note: in order to use the M-. command, your file needs to be in a Cabal project, or haskell-mode will ask to create a temporary one.The third feature that haskell-mode provides without interaction with...
This was quite hard to get right, but it's very stable and fast now. All kinds of memory, connection and source image errors need to be handled and recovered from correctly, and the cache needs to purge the correct images when capacity is hit, all with potentially dozens of threads. ...
Hint: If you get a compiler warning when -Wall and -Wextra are turned on, this is a strong sign that there is an error in your program, despite the fact that the compiler is able to compile it. Warnings mean that the compiler thinks ...
This makes it easy to define the element-wise sum of two tensors, or a general element-wise binary operation: tenAdd :: Num n => Tensor n -> Tensor n -> Tensor n tenAdd = tenZipWith (Scalar . uncurry (+), Vector) tenBinOp :: (a -> b -> c) -> Tensor a -> Tensor b ...
