scipy.linalg.lapack.cgehrd

scipy.linalg.lapack.cgehrd = <fortran object>
cgehrd - Function signature:
ht,tau,info = cgehrd(a,[lo,hi,lwork,overwrite_a])
Required arguments:
a : input rank-2 array(‘F’) with bounds (n,n)
Optional arguments:
lo := 0 input int hi := n-1 input int overwrite_a := 0 input int lwork := MAX(n,1) input int
Return objects:
ht : rank-2 array(‘F’) with bounds (n,n) and a storage tau : rank-1 array(‘F’) with bounds (n - 1) info : int
