scipy.linalg.lapack.zgges

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

zgges - Function signature:

a,b,sdim,alpha,beta,vsl,vsr,work,info = zgges(zselect,a,b,[jobvsl,jobvsr,sort_t,ldvsl,ldvsr,lwork,zselect_extra_args,overwrite_a,overwrite_b])

Required arguments:

zselect : call-back function a : input rank-2 array(‘D’) with bounds (lda,*) b : input rank-2 array(‘D’) with bounds (ldb,*)

Optional arguments:

jobvsl := 1 input int jobvsr := 1 input int sort_t := 0 input int zselect_extra_args := () input tuple overwrite_a := 0 input int overwrite_b := 0 input int ldvsl := ((jobvsl==1)?n:1) input int ldvsr := ((jobvsr==1)?n:1) input int lwork := 2*n input int

Return objects:

a : rank-2 array(‘D’) with bounds (lda,*) b : rank-2 array(‘D’) with bounds (ldb,*) sdim : int alpha : rank-1 array(‘D’) with bounds (n) beta : rank-1 array(‘D’) with bounds (n) vsl : rank-2 array(‘D’) with bounds (ldvsl,n) vsr : rank-2 array(‘D’) with bounds (ldvsr,n) work : rank-1 array(‘D’) with bounds (MAX(lwork,1)) info : int

Call-back functions:

def zselect(alpha,beta): return zselect Required arguments:

alpha : input complex beta : input complex

Return objects:

zselect : int
