  2. Time-scale calculus - Wikipedia

    en.wikipedia.org/wiki/Time-scale_calculus

    A time scale (or measure chain) is a closed subset of the real line. The common notation for a general time scale is T {\displaystyle \mathbb {T} } . The two most commonly encountered examples of time scales are the real numbers R {\displaystyle \mathbb {R} } and the discrete time scale h Z {\displaystyle h\mathbb {Z} } .

  3. Time scale - Wikipedia

    en.wikipedia.org/wiki/Time_scale

    Time scale may refer to: Time standard, a specification of either the rate at which time passes, points in time, or both; A duration or quantity of time: Orders of magnitude (time) as a power of 10 in seconds; A specific unit of time; Geological time scale, a scale that divides up the history of Earth into scientifically meaningful periods

  4. File:OBJECT COUNTING AND DENSITY CALCULATION USING MATLAB.pdf

    en.wikipedia.org/wiki/File:OBJECT_COUNTING_AND...

    Knowing the number of objects present in the image can be useful for further analysis in a wide range of applications. In this project we propose a simple method for automatically determining the number of objects in an image . Once the number of objects are determined the objects per unit area or the density can also be estimated.

  5. Time series - Wikipedia

    en.wikipedia.org/wiki/Time_series

    The total number of deaths declined in every year until the mid-1980s, after which there were occasional increases, often proportionately - but not absolutely - quite large. A study of corporate data analysts found two challenges to exploratory time series analysis: discovering the shape of interesting patterns, and finding an explanation for ...

  6. Discrete time and continuous time - Wikipedia

    en.wikipedia.org/wiki/Discrete_time_and...

    The variable "time" ranges over the entire real number line, or depending on the context, over some subset of it such as the non-negative reals. Thus time is viewed as a continuous variable . A continuous signal or a continuous-time signal is a varying quantity (a signal ) whose domain, which is often time, is a continuum (e.g., a connected ...

  7. MATLAB - Wikipedia

    Variables are defined using the assignment operator, =. MATLAB is a weakly typed programming language because types are implicitly converted. [35] It is an inferred typed language because variables can be assigned without declaring their type, except if they are to be treated as symbolic objects, [36] and that their type can change.

  8. Value change dump - Wikipedia

    en.wikipedia.org/wiki/Value_change_dump

    The variable definition section of the VCD file contains scope information as well as lists of signals instantiated in a given scope. Each variable is assigned an arbitrary identifier for use in the value change section. The identifier is composed of one or more printable ASCII characters from ! to ~ (decimal 33 to 126), these are

  9. List of numerical libraries - Wikipedia

    en.wikipedia.org/wiki/List_of_numerical_libraries

    GNU Octave is an open source high level programming language and library, including a command line interface and GUI, analogous to commercial alternatives such as Maple, MATLAB, Mathematica, etc. APIs, functions and libraries can be called from many platforms, including high level engineering programs, where functions are, in many cases ...
