scipy.linalg.lapack.zgbtrf

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

zgbtrf - Function signature:

lu,ipiv,info = zgbtrf(ab,kl,ku,[m,n,ldab,overwrite_ab])

Required arguments:

ab : input rank-2 array(‘D’) with bounds (ldab,*) kl : input int ku : input int

Optional arguments:

m := shape(ab,1) input int n := shape(ab,1) input int overwrite_ab := 0 input int ldab := shape(ab,0) input int

Return objects:

lu : rank-2 array(‘D’) with bounds (ldab,*) and ab storage ipiv : rank-1 array(‘i’) with bounds (MIN(m,n)) info : int
