  2. SAS language - Wikipedia

    en.wikipedia.org/wiki/SAS_language

    The SAS system was originally a single instruction, single data (SISD) engine, but single instruction, multiple data (SIMD) and multiple instruction, multiple data (MIMD) functionality was later added. [9] Most base SAS code can be ported between versions, but some are functions and parameters are specific to certain operating systems and ...

  3. SAS (software) - Wikipedia

    en.wikipedia.org/wiki/SAS_(software)

    SAS provides a graphical point-and-click user interface for non-technical users and more through the SAS language. [3] SAS programs have DATA steps, which retrieve and manipulate data, PROC (procedures) which analyze the data, and may also have functions. [4] Each step consists of a series of statements. [5]

  4. Condition number - Wikipedia

    en.wikipedia.org/wiki/Condition_number

    Condition numbers can also be defined for nonlinear functions, and can be computed using calculus.The condition number varies with the point; in some cases one can use the maximum (or supremum) condition number over the domain of the function or domain of the question as an overall condition number, while in other cases the condition number at a particular point is of more interest.

  5. Supervisory attentional system - Wikipedia

    en.wikipedia.org/wiki/Supervisory_attentional_system

    Some common functions characterized by the SAS are planning, inhibition, and abstraction of logical rules. These processes were measured using specifically designed tasks, the Tower of London (TOL) , Hayling test , and Brixton test , respectively, and used for the comparison between patients with frontal lobe lesions and control individuals.

  6. Cross-correlation - Wikipedia

    en.wikipedia.org/wiki/Cross-correlation

    Animation of how cross-correlation is calculated. The left graph shows a green function G that is phase-shifted relative to function F by a time displacement of 𝜏. The middle graph shows the function F and the phase-shifted G represented together as a Lissajous curve. Integrating F multiplied by the phase-shifted G produces the right graph ...

  7. Rosenbrock function - Wikipedia

    en.wikipedia.org/wiki/Rosenbrock_function

    Plot of the Rosenbrock function of two variables. Here a = 1 , b = 100 {\displaystyle a=1,b=100} , and the minimum value of zero is at ( 1 , 1 ) {\displaystyle (1,1)} . In mathematical optimization , the Rosenbrock function is a non- convex function , introduced by Howard H. Rosenbrock in 1960, which is used as a performance test problem for ...

  8. Hard disk drive interface - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive_interface

    The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses a mechanically identical data and power connector to standard 3.5-inch SATA1/SATA2 HDDs, and many server-oriented SAS RAID controllers are also capable of addressing SATA hard drives.

  9. User-defined function - Wikipedia

    en.wikipedia.org/wiki/User-defined_function

    In the COBOL programming language, a user-defined function is an entity that is defined by the user by specifying a FUNCTION-ID paragraph. A user-defined function must return a value by specifying the RETURNING phrase of the procedure division header and they are invoked using the function-identifier syntax.
