Nov 12, 2010 · The way I did it for my own little tensor package is to tensor product the two together, transpose both of the relevant indices you want to contract to the first indices, then run Tr to contract them (call it

Flatten [ f [ e, …]] は，頭部が f の部分式を平坦にする．. m ij が行列のとき， Flatten [ { { m 11, m 12 }, { m 21, m 22 } }, { { 1, 3 }, { 2, 4 } }] は，実質的に「ブロック」 m ij から単一の行列を構築する．. Flatten [ list, { { i 1 }, { i 2 }, …. }] は， list 中のレベル i k が結果で ...

Flatten "unravels" lists, effectively just deleting inner braces. · Flatten[list,n] effectively flattens the top level in list n times. · Flatten[f[e,…]] · If the ...

Flatten [ list, { { i 1 }, { i 2 }, … }] effectively transposes levels in list, putting level i k in list at level k in the result. Note that the function Transpose in effect uses an inverse of this specification. Flatten flattens out levels in SparseArray objects just as in the corresponding ordinary arrays. ».

HoldPattern[Flatten[l_, lev_]] :> Map[Flatten, l, lev]] and you can check that it will give the same result for the above example. The difference is that in this case, only the explicit entries of Flatten in code will be affected.

Partition[ ] - Opposite of flatten: groups items into a nested list. Transpose[ ] - Switches columns to rows and rows to columns. Page 2. Department of ...

ArrayFlatten can be used to form block matrices from arrays of blocks. For a matrix of matrices, ArrayFlatten [ a] yields a matrix whose elements are in the same order as in MatrixForm [ a]. ArrayFlatten [ a] is normally equivalent to Flatten [ a, { { 1, 3 }, { 2, 4 } }]. ».

My question is if there is a way to do this without using Flatten twice. I hope I explained it well. Share.

31.05.2021 · 然而，在Mathematica程序中，我们经常会修改一个列表，它不是原始列表，而是一个副本，这样原始列表就不会改变。这种编程风格可以说更简洁，但由于复制了原始对象，因此需要更多内存。 ... [Flatten[step4list]] {1, 2, 5, 6}
