F＃多维数组理解

Question

Is there a syntax for creating multidimensional array using comprehensions is F#? This is really easy for jagged arrays:

let weights1 = [|
                  [|3.0|]
                  [|1.0|]
               |]

Sure that I can than convert this jagged array to multidimensional array:

let weights = Array2D.init 2 2 (fun i j -> weights1.[i].[j])

But isn't there a syntax way of doing the same?

Answer 1

使用array2D ^MSDN运算符，传递一系列序列（或锯齿状数组）：

array2D [[3.0]; [1.0]]
