Julia: 2d array assignment












0















I'm trying to do the assignment in the 2d array with the nested loop. I'm trying to access the elements of the array as follows. But I get a mistake. I've searched, but I didn't get results. How can I assign Julia in the 2d array?



for x in 1:total

          for y in 1:W

            @show (x, y)

            if agirliklar[x] <= y



                V[x][y] = getMax(V[x-1][y], degerler[x] + V[x-1][y - agirliklar[x]])





            else

                print("sa")

                V[x][y] = V[x-1][y]

            end

          end

end

  • It would be useful to see (example) definitions of total, W, agirliklar, degerler, and V. But maybe it's just that x-1 is one-off?

In Julia arrays are 1-based not 0-based.



You try to access V[x-1] where x can take value of 1.



Site note: always provide a minimum working example (MWE) rather than just dumping a part of your production code.

    (At least) two things are wrong here:




    1. As @PrzemyslawSzufel says, ordinary Julia arrays are 1-indexed, so you cannot access them at index zero. Though it is possible to get special arrays that are 0-indexed.

    2. If V is a 2D array, as you are saying, you cannot access it like this: V[x][y]. Instead you access them like this: V[x, y]. You can read more about this here: https://docs.julialang.org/en/v1/manual/arrays/#man-array-indexing-1

            Monofisismo

            Image
            Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri

A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México
