我已经定义了以下类型(从代码中简化):
type Polynomial<'a when 'a :(static member public Zero : 'a)
and 'a: (static member (+): 'a*'a -> 'a)
and 'a : (static member (*): 'a*'a -> 'a) > =
| Polynomial of 'a list

static member inline (+) (x: Polynomial<'a> , y : Polynomial<'a>) : Polynomial<'a>=
match x,y with
|Polynomial xlist, Polynomial ylist ->
let longer, shorter =
if xlist.Length> ylist.Length then xlist, ylist
else ylist, xlist
let shorterExtended = List.append shorter (List.init (longer.Length - shorter.Length) (fun _ …Run Code Online (Sandbox Code Playgroud) 我无法使用Python C API打开numpy。我有以下代码

我刚开始使用英特尔Fortran编译器和Visual Studio 2015在Fortran中使用OpenMP.在项目属性中,我将"Fortran - >语言 - >处理OpenMP指令"设置为"生成并行代码(/ Qopenmp)"
我有一个简单的程序,如下所示:
program hellothreads
integer threads, id
call omp_set_num_threads(3)
threads = omp_get_num_threads()
print *,"there are", threads, "threads"

当然没有.设置线程数似乎可以正常工作,因为:
!$OMP Parallel private(id) shared(threads)
threads = omp_get_num_threads()
id = omp_get_thread_num()
print *, "hello from thread", id, "out of", threads
!$OMP end Parallel
