subroutine ddpow1(n,v,iv,p,ip,rr,ri,ir,ierr,iscmpl)
c!purpose
c computes V^P with V and P real vectors
c!calling sequence
c subroutine ddpow1(n,v,iv,p,ip,rr,ri,ir,ierr,iscmpl)
c integer n,iv,ip,ir,ierr,iscmpl
c double precision v(*),p(*),rr(*),ri(*)
c
c n : number of elements of V and P vectors
c v : array containing V elements V(i)=v(1+(i-1)*iv)
c iv : increment between two V elements in v (may be 0)
c p : array containing P elements P(i)=p(1+(i-1)*ip)
c ip : increment between two P elements in p (may be 0)
c rr : array containing real part of the results vector R:
c real(R(i))=rr(1+(i-1)*ir)
c ri : array containing imaginary part of the results vector R:
c imag(R(i))=ri(1+(i-1)*ir)
c ir : increment between two R elements in rr and ri
c ierr : error flag
c ierr=0 if ok
c ierr=1 if 0**0
c ierr=2 if 0**k with k<0
c iscmpl :
c iscmpl=0 if result is real
c iscmpl=1 if result is complex
