在<>Fortran>上,我们编码如下:
!vectors w,q are of the same size ... w = ... !a vector of integers [0,...,n) if (allocated(t)) deallocate(t); allocate(t(count(w/=0))) t = pack(q, w/=0) m = count(t>0) if (allocated(b)) deallocate(b) allocate(b(m)) b = pack(t,t>0)
翻译Python:
t = q[w!=0] b = t[t>0]
我们不能确定我们确实执行的那部分方案是正确的。 请注意,它是一个非常大的方案的一部分,我们正在发现一些time误,有时甚至没有电文,但坠毁......
在F2003,将t和b宣布为可分配的病媒,仅写上:
t = pack(q, w/=0)
b = pack(t,t>0)
一些汇编者(GCC 4.6)支持这项工作,这些汇编者包括:
