scipy.linalg.lapack.zgees

scipy.linalg.lapack.zgees = <fortran object>

zgees - Function signature:

t,sdim,w,vs,work,info = zgees(zselect,a,[compute_v,sort_t,lwork,zselect_extra_args,overwrite_a])

Required arguments:

zselect : call-back function a : input rank-2 array(‘D’) with bounds (n,n)

Optional arguments:

compute_v := 1 input int sort_t := 0 input int zselect_extra_args := () input tuple overwrite_a := 0 input int lwork := 3*n input int

Return objects:

t : rank-2 array(‘D’) with bounds (n,n) and a storage sdim : int w : rank-1 array(‘D’) with bounds (n) vs : rank-2 array(‘D’) with bounds (ldvs,n) work : rank-1 array(‘D’) with bounds (MAX(lwork,1)) info : int

Call-back functions:

def zselect(arg): return zselect Required arguments:

arg : input complex

Return objects:

zselect : int
