complib/BISECT(3) -- EISPACK routine. This subroutine finds those eigenvalues of a TRIDIAGONAL SYMMETRIC matrix which lie in a spec
|
|
On INPUT N is the order of the matrix. EPS1 is an absolute error tolerance for the computed eigenvalues. If the input EPS1 is non-positive, it is reset for each submatrix to a default value, namely, minus the product of the relative machine precision and the 1-norm of the submatrix. D contains the diagonal elements of the input matrix. E contains the subdiagonal elements of the input matrix in its last N-1 positions. E(1) is arbitrary. E2 contains the squares of the corresponding elements of E. ... |

Tk/bitmap(3) -- Images that display two colors
|
|
A bitmap is an image whose pixels can display either of two colors or be transparent. A bitmap image is defined by four things: a background color, a foreground color, and two bitmaps, called the source and the mask. Each of the bitmaps specifies 0/1 values for a rectangular array of pixels, and the two bitmaps must have the same dimensions. For pixels where the mask is zero, the image displays nothing, producing a transparent effect. For other pixels, the image displays the foreground color if ... |

standard/blankscreen(3) -- controls screen blanking
|
|
b expects TRUE or FALSE. TRUE stops display and turns screen black. FALSE restores the display. |
|
standard/blanktime(3) -- sets the screen blanking timeout
|
|
count expects the number of graphics timer events after which to blank the current screen. The frequency of graphics timer events is returned by the getgdesc inquiry GD_TIMERHZ. |

standard/blendcolor(3) -- specifies a constant color for blending
|
|
red is a floating point value between 0 and 1 (default 1.0). green is a floating point value between 0 and 1 (default 1.0). blue is a floating point value between 0 and 1 (default 1.0). alpha is a floating point value between 0 and 1 (default 1.0). |

standard/blendfunction(3) -- computes a blended color value for a pixel
|
|
sfactr is a symbolic constant taken from the list below. It identifies the blending factor by which to scale contribution from source pixel RGBA (red, green, blue, alpha) values. BF_ZERO 0 BF_ONE 1 BF_DC (destination RGBA)/255 BF_MDC 1 - (destination RGBA)/255 BF_SA (source alpha)/255 BF_MSA 1 - (source alpha)/255 BF_DA (destination alpha)/255 BF_MDA 1 - (destination alpha)/255 BF_MIN_SA_MDA min(BF_SA, BF_MDA) BF_CC (constant RGBA)/255 BF_MCC 1 - (constant RGBA)/255 BF_CA (constant alpha)/255 BF... |

perl5/blib(3) -- Use MakeMaker's uninstalled version of a package
|
|
Looks for MakeMaker-like 'blib' directory structure starting in dir (or current directory) and working back up to five levels of '..'. Intended for use on command line with -M option as a way of testing arbitary scripts against an uninstalled version of a package. However it is possible to : use blib; or use blib '..'; etc. if you really must. |

standard/blink(3) -- changes a color map entry at a selectable rate
|
|
rate expects the number of vertical retraces per blink. On the standard monitor, there are 60 vertical retraces per second. i expects an index into the current color map. The color defined at that index is the color that is blinked (alternated). red expects the red value of the alternate color that blinks against the color selected from the color map by the i parameter. green expects the green value of the alternate color that blinks against the color selected from the color map by the i paramet... |
|
standard/blkqread(3) -- reads multiple entries from the queue
|
|
data expects a pointer to the buffer that is to receive the queue information. n expects the number of elements in the buffer. FUNCTION RETURN VALUE The returned value of the function is the number of 16 bit words of data actually read into the data buffer. Note that this number will be twice the number of complete queue entries read, because each queue entry consists of two 16 bit words. |

ftn/bool(3) -- FORTRAN bitwise boolean functions
|
|
bool is the general name for the bit field manipulation intrinsic functions and subroutines from the FORTRAN Military Standard (MIL-STD1753). and, or and xor return the value of the binary operations on their arguments. not is a unary operator returning the one's complement of its argument. ior, iand, not, ieor - return the same results as and, or, not, and xor. lshift and rshift return the value of the first argument shifted left or right, respectively, the number of times specified by the sec... |

complib/BQR(3) -- EISPACK routine. This subroutine finds the eigenvalue of smallest (usually) magnitude of a REAL SYMMETRIC BAND
|
|
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. MB is the (half) band width of the matrix, defined as the number of adjacent diagonals, including the principal diagonal, required to specify the non-zero portion of the lower triangle of the matrix. A contains the lower triangle of the symmetric band input matrix stored as an N by MB array. Its lowest subdiagonal is stored in the ... |

Tcl/break(3) -- Abort looping command
|
|
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which causes a break exception to occur. The exception causes the current script to be aborted out to the the innermost containing loop command, which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch command, Tk event bindings, and the outermost scripts of procedure bodies.... |

bsearch(3c) -- binary search a sorted table
|
|
bsearch is a binary search routine generalized from Knuth (6.2.1) Algorithm B. It returns a pointer into a table (an array) indicating where a datum may be found or a null pointer if the datum cannot be found. The table must be previously sorted in increasing order according to a comparison function pointed to by compar. key points to a datum instance to be sought in the table. base points to the element at the base of the table. nel is the number of elements in the table. s... |
