  3. JData - Wikipedia

    en.wikipedia.org/wiki/JData

    The initial development of the JData annotation scheme started in 2011 as part of the development of the JSONLab Toolbox - a widely used open-source MATLAB/GNU Octave JSON reader/writer. The majority of the annotated N-D array constructs, such as _ArrayType_ , _ArraySize_ , and _ArrayData_ , had been implemented in the early releases of JSONLab .

  4. MATLAB - Wikipedia

    en.wikipedia.org/wiki/MATLAB

    MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities.

    en.wikipedia.org/wiki/Unum_(number_format)

    Unums (universal numbers [1]) are a family of number formats and arithmetic for implementing real numbers on a computer, proposed by John L. Gustafson in 2015. [2] They are designed as an alternative to the ubiquitous IEEE 754 floating-point standard. The latest version is known as posits. [3]

  6. Epoch (computing) - Wikipedia

    en.wikipedia.org/wiki/Epoch_(computing)

    Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...

    The program interactively converts dates from Julian to MDY and vice versa. Results are displayed on line 24 of the terminal. It accepts two parameters. The &IN parameter which is the date string to be converted. If a Julian string it should be in the format YYNNN where YY is the year number and NNN is the day number of the year.

  8. Data acquisition - Wikipedia

    en.wikipedia.org/wiki/Data_acquisition

    Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing.
