|
|
CHPSV computes the solution to a complex system of linear equations A * X = B, where A is an N-by-N Hermitian matrix stored in packed format and X and B are N-by-NRHS matrices. The diagonal pivoting method is used to factor A as A = U * D * U**H, if UPLO = 'U', or A = L * D * L**H, if UPLO = 'L', where U (or L) is a product of permutation and unit upper (lower) triangular matrices, D is Hermitian and block diagonal with 1-by-1 and 2-by-2 diagonal blocks. The factored form of A is then used t... |

|
|
CHPSVX uses the diagonal pivoting factorization A = U*D*U**H or A = L*D*L**H to compute the solution to a complex system of linear equations A * X = B, where A is an N-by-N Hermitian matrix stored in packed format and X and B are N-by-NRHS matrices.

complib/chsein(3) -- use inverse iteration to find specified right and/or left eigenvectors of a complex upper Hessenberg matrix H
|
|
CHSEIN uses inverse iteration to find specified right and/or left eigenvectors of a complex upper Hessenberg matrix H. The right eigenvector x and the left eigenvector y of the matrix H corresponding to an eigenvalue w are defined by: H * x = w * x, y**h * H = w * y**h where y**h denotes the conjugate transpose of the vector y. |

|
CHSEQR computes the eigenvalues of a complex upper Hessenberg matrix H, and, optionally, the matrices T and Z from the Schur decomposition H = Z T Z**H, where T is an upper triangular matrix (the Schur form), and Z is the unitary matrix of Schur vectors. Optionally Z may be postmultiplied into an input unitary matrix Q, so that this routine can give the Schur factorization of a matrix A which has been reduced to the Hessenberg form H by the unitary matrix Q: A = Q*H*Q**H = (QZ)*T*(QZ)**H.... |

standard/chunksize(3) -- specifies minimum object size in memory
|
|
chunk Expects the minimum memory size to allocate for an object. As you add objects to a display list, chunk is the unit size (in bytes) by which the memory allocated to the display list grows. |

|
|
On INPUT NM must be set to the row dimension of two-dimensional array parameters as declared in the calling program dimension statement. N is the order of the matrix. AR and AI contain the real and imaginary parts, respectively, of the Hessenberg matrix. WR and WI contain the real and imaginary parts, respectively, of the eigenvalues of the matrix. The eigenvalues must be stored in a manner identical to that of subroutine COMLR, which recognizes possible splitting of the matrix. SELECT specifies... |

ckpt_create(3) -- checkpoint and restart (CPR) library interfaces
|
|
The functions provided here are used to issue checkpoint and restart (CPR) requests to a process or group of processes. The ckpt_setup, ckpt_create, ckpt_restart, and ckpt_remove routines are implemented according to the IEEE standard POSIX 1003.1m Draft 1, with minor modifications (described below). The ckpt_stat function is an IRIX extension. Silicon Graphics intends to follow the future development of POSIX 1003.1m draft standards and endeavor to be compliant. ckpt_setup This routine currentl... |
