Array2 initialization
f#

Hello,

I'm looking at using the array2 type.
Is there a way to initialize it the same way as it is done in C#, i.e. :

int[,] array = new int[3, 3] { { 1, 2, 3 }, { 5, 6, 7 }, { 8, 9, 0} };

Because the nb of elements is big, I'd like to avoid having to individually set each element like this :
arr.(x,y) = z

Thanks,

v.

.

There isn't away to exactly as you'd like, however you can create a "jagged array" like that very easily:

1

let arr = [| [| 1; 2 |] ; [| 1; 2 |] |]

The syntax to access is slightly different:

1

let x =arr.(0).(0)

The only really difference is that all subarrays are not guaranteed to be equal. If you really need a matrix style array it should be fairly easy to write a function to transform a jagged array into a matrix.

Cheers,
Rob

Cool ! The jagged array will do.
Thanks,
