多线程编程示例(此处为CPU和I/O任务同时进行): /// A simple prime number detector let isPrime (n:int) = let bound = int (sqrt (float n)) seq {2 .. bound} |> Seq.forall (fun x -> n % x
数学上,数域F上的n阶正交群,记作O(n,F),是F上的n×n 正交矩阵在矩阵乘法下构成的群。它是一般线性群GL(n,F)的子群,由 O ( n , F ) = { Q ∈ G L ( n , F ) ∣ Q T Q = Q Q T = I } {\displaystyle \mathrm {O} (n,F)=\{Q\in
