|
|
DSYTRD reduces a real symmetric matrix A to real symmetric tridiagonal form T by an orthogonal similarity transformation: Q**T * A * Q = T. |

complib/dsytrf(3) -- Bunch-Kaufman diagonal pivoting method
|
|
DSYTRF computes the factorization of a real symmetric matrix A using the Bunch-Kaufman diagonal pivoting method. The form of the factorization is A = U*D*U**T or A = L*D*L**T where U (or L) is a product of permutation and unit upper (lower) triangular matrices, and D is symmetric and block diagonal with 1-by-1 and 2-by-2 diagonal blocks. This is the blocked version of the algorithm, calling Level 3 BLAS.... |

|
|
DSYTRI computes the inverse of a real symmetric indefinite matrix A using the factorization A = U*D*U**T or A = L*D*L**T computed by DSYTRF. |

complib/dsytrs(3) -- solve a system of linear equations A*X = B with a real symmetric matrix A using the factorization A = U*D*U**T
|
|
DSYTRS solves a system of linear equations A*X = B with a real symmetric matrix A using the factorization A = U*D*U**T or A = L*D*L**T computed by DSYTRF. |

audiocddat/DTaddcallback(3d) -- set a callback for the DAT audio data parser
|
|
dtp A pointer to the target DTPARSER. type The type of callback being set. DTDATATYPES is an enumerated type defined in dataudio.h containing the following values: dt_audio, dt_pnum, dt_index, dt_ptime, dt_atime, dt_rtime, dt_prortime, dt_mainid, dt_sampfreq, dt_toc, dt_date, dt_catalog, dt_ident, dt_probinary. func A pointer to the function to be called. arg A user supplied argument that is passed to the callback function.... |

audiocddat/DTatohmsf(3d) -- convert ASCII string to hours, minutes, seconds, frames
|
|
str A pointer to the ASCII string to be converted. h A pointer to the location to store the hours value. m A pointer to the location to store the minutes value. s A pointer to the location to store the seconds value. f A pointer to the location to store the frame value. |
|
audiocddat/DTatotime(3d) -- convert ASCII string to timecode
|
|
tc A pointer to the struct dttimecode in which to place the result. s A pointer to the ASCII string to be converted. The string pointed at by s must be at least 11 bytes long not counting the terminating null. |
|
complib/dtbcon(3) -- band matrix A, in either the 1-norm or the infinity-norm
|
|
DTBCON estimates the reciprocal of the condition number of a triangular band matrix A, in either the 1-norm or the infinity-norm. The norm of A is computed and an estimate is obtained for norm(inv(A)), then the reciprocal of the condition number is computed as RCOND = 1 / ( norm(A) * norm(inv(A)) ). |
|
complib/dtbrfs(3) -- provide error bounds and backward error estimates for the solution to a system of linear equations with a tria
|
|
DTBRFS provides error bounds and backward error estimates for the solution to a system of linear equations with a triangular band coefficient matrix. The solution matrix X must be computed by DTBTRS or some other means before entering this routine. DTBRFS does not do iterative refinement because doing so cannot improve the backward error. |
|
complib/dtbtrs(3) -- B,
|
|
DTBTRS solves a triangular system of the form where A is a triangular band matrix of order N, and B is an N-by NRHS matrix. A check is made to verify that A is nonsingular. |
|
audiocddat/DTcreateparser(3d) -- creates a DAT audio data parser
|
|
Upon successful completion, DTcreateparser returns a pointer to a DTPARSER, an opaque type defined in dataudio.h. Otherwise a value of null (0) is returned. |
|
audiocddat/DTdeleteparser(3d) -- deletes a DAT audio data parser
|
|
dtp A pointer to the DTPARSER to be deleted. |
|
audiocddat/DTframetohmsf(3d) -- convert DAT frame number to hours, minutes, seconds, frame
|
|
fr The frame number to be converted. h A pointer to the location to store the hours value. m A pointer to the location to store the minutes value. s A pointer to the location to store the seconds value. f A pointer to the location to store the frame value. |
