Answer 1

I assume you are using Microsoft.FSharp.Math.

In this case you have to use 'init' function from Matrix.Generic module:

let matrix1 = Matrix.Generic.init 3 3 (fun i j -> complex 1.0 0.0)

> 

val matrix1 : Matrix<complex> = matrix [[1r+0i; 1r+0i; 1r+0i]
                                        [1r+0i; 1r+0i; 1r+0i]
                                        [1r+0i; 1r+0i; 1r+0i]]
