As above, I want to initialise a large (4096 by 4096) matrix. Ideally I’d want to do so statically, but there’s no documentation on doing so with random
f64 so I want to check understanding with DMatrix first, as there are better code snippets.
let dm3 DMatrix::new_random(4096, 4096) fails due to failing to infer type. That… makes sense, actually, I want an f64 and haven’t specified one. But it also fails with smaller dimensions like (4,3) it also fails. Finally, I checked the reference example for
let dm3 = DMatrix::identity(4, 3); //this is the the reference example! | --- ^^^^^^^^^^^^^^^^^ cannot infer type for type parameter `N`
If I do put in a type argument, it’s unexpected:
l let dm3 = DMatrix::new_random::<f64>(4, 3); | ^^^ unexpected type argument
So, how do
