scipy.linalg.lapack.cgeqp3

scipy.linalg.lapack.cgeqp3 = <fortran object>
cgeqp3 - Function signature:
qr,jpvt,tau,work,info = cgeqp3(a,[lwork,overwrite_a])
Required arguments:
a : input rank-2 array(‘F’) with bounds (m,n)
Optional arguments:
overwrite_a := 0 input int lwork := 3*(n+1) input int
Return objects:
qr : rank-2 array(‘F’) with bounds (m,n) and a storage jpvt : rank-1 array(‘i’) with bounds (n) tau : rank-1 array(‘F’) with bounds (MIN(m,n)) work : rank-1 array(‘F’) with bounds (MAX(lwork,1)) info : int
