[julia-users] How to convert a matrix in Julia ?

[Lytu]

Hello Julia users,

How can i convert an Array{Int32,2} matrix H in an Array{Float64,2} matrix?

For example: H=[5 3 6;3 9 12;6 12 17] 

I ask this because i would like to do this:   H=[5 3 6;3 9 12;6 12 17] 
                                                              
val=-7.046128291045994
                                                              H[2,1] = val
but it gives an error: InexactError()

I think it is because "val" is a* float64* and the "matrix H" is an 
*Array{Int32,2}*

Does anybody know how i can do this?

Thanks
