NAME
PDL::LinearAlgebra::Complex - PDL interface to the lapack linear algebra programming
library (complex number)
SYNOPSIS
use PDL::Complex
use PDL::LinearAlgebra::Complex;
$a = r2C random (100,100);
$s = r2C zeroes(100);
$u = r2C zeroes(100,100);
$v = r2C zeroes(100,100);
$info = 0;

cgesdd($a, $job, $info, $s , $u, $v);
# or, using native complex numbers:
use PDL;
use PDL::LinearAlgebra::Complex;
$a = random(cdouble, 100, 100);
$s = zeroes(cdouble, 100);
$u = zeroes(cdouble, 100, 100);
$v = zeroes(cdouble, 100, 100);
$info = 0;

DESCRIPTION
This module provides an interface to parts of the lapack library (complex numbers). These
routines accept either float or double ndarrays. #line 79 "Complex.pm"
FUNCTIONS
cgtsv
Signature: ([phys]DL(2,n); [phys]D(2,n); [phys]DU(2,n); [io,phys]B(2,n,nrhs); int [o,phys]info())
Solves the equation
A * X = B
where A is an "n" by "n" tridiagonal matrix, by Gaussian elimination with partial
pivoting, and B is an "n" by "nrhs" matrix.
Note that the equation "A**T*X = B" may be solved by interchanging the order of the
arguments DU and DL.
NB This differs from the LINPACK function "cgtsl" in that "DL" starts from its first
element, while the LINPACK equivalent starts from its second element.
Arguments
=========
DL: On entry, DL must contain the (n-1) sub-diagonal elements of A.
On exit, DL is overwritten by the (n-2) elements of the
second super-diagonal of the upper triangular matrix U from
the LU factorization of A, in DL(1), ..., DL(n-2).
D: On entry, D must contain the diagonal elements of A.
On exit, D is overwritten by the n diagonal elements of U.
DU: On entry, DU must contain the (n-1) super-diagonal elements of A.
On exit, DU is overwritten by the (n-1) elements of the
first super-diagonal of the U.
B: On entry, the n by nrhs matrix of right hand side matrix B.
On exit, if info = 0, the n by nrhs solution matrix X.
info: = 0: successful exit
< 0: if info = -i, the i-th argument had an illegal value
> 0: if info = i, U(i,i) is exactly zero, and the solution
has not been computed. The factorization has not been
completed unless i = n.
use PDL::Complex;
$dl = random(float, 9) + random(float, 9) * i;

$b = random(10,5) + random(10,5) * i;
cgtsv($dl, $d, $du, $b, ($info=null));
print "X is:\n$b" unless $info;

Signature: ([phys]a(2,n);int [phys]inca();[phys]b(2,n);int [phys]incb();[o,phys]c(2))
Forms the dot product of two vectors, conjugating the first vector.
caxpy
Signature: ([phys]a(2,n);int [phys]inca();[phys] alpha(2);[io,phys]b(2,n);int [phys]incb())
Complex version of axpy
cnrm2
Signature: ([phys]a(2,n);int [phys]inca();[o,phys]b())
Complex version of nrm2
casum
Signature: ([phys]a(2,n);int [phys]inca();[o,phys]b())
Complex version of asum
cscal
Signature: ([io,phys]a(2,n);int [phys]inca();[phys]scale(2))
Complex version of scal
sscal
Signature: ([io,phys]a(2,n);int [phys]inca();[phys]scale())
Scales a complex vector by a real constant.
sscal ignores the bad-value flag of the input ndarrays. It will set the bad-value flag of
all output ndarrays if the flag is set for any of the input ndarrays.
crotg
Signature: ([io,phys]a(2);[phys]b(2);[o,phys]c(); [o,phys]s(2))
Complex version of rotg
clacpy
Signature: ([phys]A(2,m,n); int uplo(); [o,phys]B(2,p,n))
Complex version of lacpy
claswp
Signature: ([io,phys]A(2,m,n); int [phys]k1(); int [phys]k2(); int [phys]ipiv(p);int [phys]inc())
Complex version of laswp
ctricpy
Signature: (A(c=2,m,n);int uplo();[o] C(c=2,m,n))
Copy triangular part to another matrix. If uplo == 0 copy upper triangular part.
ctricpy does not process bad values. It will set the bad-value flag of all output
ndarrays if the flag is set for any of the input ndarrays.
cmstack
Signature: (x(c,n,m);y(c,n,p);[o]out(c,n,q))
Combine two 3D ndarrays into a single ndarray. This routine does backward and forward
dataflow automatically.
cmstack does not process bad values. It will set the bad-value flag of all output
ndarrays if the flag is set for any of the input ndarrays.
ccharpol
Signature: ([phys]A(c=2,n,n);[phys,o]Y(c=2,n,n);[phys,o]out(c=2,p);)
Complex version of charpol
