scipy.linalg.lapack.chbevx

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

chbevx - Function signature:

w,z,m,ifail,info = chbevx(ab,vl,vu,il,iu,[ldab,compute_v,range,lower,abstol,mmax,overwrite_ab])

Required arguments:

ab : input rank-2 array(‘F’) with bounds (ldab,*) vl : input float vu : input float il : input int iu : input int

Optional arguments:

overwrite_ab := 1 input int ldab := shape(ab,0) input int compute_v := 1 input int range := 0 input int lower := 0 input int abstol := 0.0 input float mmax := (compute_v?(range==2?(iu-il+1):n):1) input int

Return objects:

w : rank-1 array(‘f’) with bounds (n) z : rank-2 array(‘F’) with bounds (ldz,mmax) m : int ifail : rank-1 array(‘i’) with bounds ((compute_v?n:1)) info : int
