|
|
SCOR2D, DCOR2D, CCOR2D and ZCOR2D compute a 2D correlation in the space domain: h(i,j) = Sum[ f(k,l) * g(i+k,j+l) ] |

SCORM1D, DCORM1D, CCORM1D and DCORM1D compute N 1D convolutions in the time domain : h(i,j) = Sum[ f(k,j) * g(i-k) ] with j=1,...,N _CORM1D can be used instead of _COR2D when the 2D filter can be decomposed into the convolution of two 1D filters. For example: ------------------ ------------------ ------------------ | 0.25 -.50 0.25 | | 0. -.50 0. | | 0. 0. 0. | | -.50 1.00 -.50 | = | 0. 1.00 0. | (*) | -.50 1.00 -.50 | | 0.25 -.50 0.25 | | 0. -.50 0. | | 0. 0. 0. | |________________| |__________... |

|
|
On INPUT NM must be set to the row dimension of two-dimensional array parameters as declared in the calling program dimension statement. LOW and IGH are integers determined by the balancing subroutine CBAL. If CBAL has not been used, set LOW=1 and IGH equal to the order of the matrix. AR and AI contain information about the unitary transformations used in the reduction by CORTH in their strict lower triangles. ORTR and ORTI contain further information about the transformations used in the reduct... |

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. LOW and IGH are integers determined by the balancing subroutine CBAL. If CBAL has not been used, set LOW=1, IGH=N. AR and AI contain the real and imaginary parts, respectively, of the complex input matrix. On OUTPUT AR and AI contain the real and imaginary parts, respectively, of the Hessenberg matrix. Information about the unitary... |

f90/cos(3) -- trigonometric functions and their inverses
|
|
The single-precision and long double-precision routines listed above are only available in the standard math library, -lm, and in -lmx. sin, cos and tan return trigonometric functions of radian arguments x for double data types. fsin, fcos and ftan, and their ANSI-named counterparts sinf, cosf and tanf return trigonometric functions of radian Page 1 TRIG(3M) TRIG(3M) arguments x for float data types. sinl, cosl and tanl do the same for long double data types. The asin routines return the arc sin... |

standard/cpack(3) -- specifies RGBA color with a single packed 32-bit integer
|
|
pack expects a packed integer containing the RGBA (red, green, blue, alpha) values you want to assign as the current color. Expressed in hexadecimal, the format of the packed integer is 0xaabbggrr, where: aa is the alpha value, bb is the blue value, gg is the green value, and rr is the red value. RGBA component values range from 0 to 0xFF (255). |

perl5/CPAN(3) -- query, download and build perl modules from CPAN sites
|
|
The CPAN module is designed to automate the make and install of perl modules and extensions. It includes some searching capabilities and knows how to use Net::FTP or LWP (or lynx or an external ftp client) to fetch the raw data from the net. Modules are fetched from one or more of the mirrored CPAN (Comprehensive Perl Archive Network) sites and unpacked in a dedicated directory. The CPAN module also supports the concept of named and versioned 'bundles' of modules. Bundles simplify the handling... |

perl5/CPAN::FirstTime(3) -- Utility for CPAN::Config file Initialization
|
|
The init routine asks a few questions and writes a CPAN::Config file. Nothing special. PPPPaaaaggggeeee 1111 |
|
perl5/CPAN::Nox(3) -- Wrapper around CPAN.pm without using any XS module
|
|
This package has the same functionality as CPAN.pm, but tries to prevent the usage of compiled extensions during it's own execution. It's primary purpose is a rescue in case you upgraded perl and broke binary compatibility somehow. |

complib/cpbcon(3) -- estimate the reciprocal of the condition number (in the 1-norm) of a complex Hermitian positive definite band
|
|
CPBCON estimates the reciprocal of the condition number (in the 1-norm) of a complex Hermitian positive definite band matrix using the Cholesky factorization A = U**H*U or A = L*L**H computed by CPBTRF. An estimate is obtained for norm(inv(A)), and the reciprocal of the condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))). |
