Question

I’m a beginner in F#. I know that there is the way to create Double Matrix using PowerPack.dll:

let B = matrix [ [ 1.0; 7.0 ];
                 [ 1.0; 3.0 ] ]

How can I create matrix with elements of my own type (for example with [,] instead of Double), so it would look like:

let B = matrix [ [ [1,2]; [3,4] ];
                 [ [7,8]; [5,6] ] ]

Answer 1

Matrix is a particularly mathematical type for working with numbers.

If you just want to arrange arbitrary elements in a rectangular shape, use standard F# lists or arrays.
