FUNCTIONS
cgtsv
Signature: (complex [phys]DL(n);complex [phys]D(n);complex [phys]DU(n);complex [io,phys]B(n,nrhs); int [o,phys]info())Solves the equation
A * X = Bwhere 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.$dl = random(float, 9) + random(float, 9) * i;

claswp
Signature: (complex [io,phys]A(m,n); int [phys]k1(); int [phys]k2(); int [phys]ipiv(p))Complex version of "laswp" in PDL::LinearAlgebra::Real
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.
