  2. Plotting algorithms for the Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Plotting_algorithms_for...

    Analogous to the exterior case, once b is found, we know that all points within the distance of b/4 from c are inside the Mandelbrot set. There are two practical problems with the interior distance estimate: first, we need to find z 0 {\displaystyle z_{0}} precisely, and second, we need to find p {\displaystyle p} precisely.

  3. Julia set - Wikipedia

    en.wikipedia.org/wiki/Julia_set

    is the smallest closed set containing at least three points which is completely invariant under f. ⁡ is the closure of the set of repelling periodic points. For all but at most two points , the Julia set is the set of limit points of the full backwards orbit (). (This suggests a simple algorithm for plotting Julia sets, see below.)

  4. Linear interpolation - Wikipedia

    en.wikipedia.org/wiki/Linear_interpolation

    Given the two red points, the blue line is the linear interpolant between the points, and the value y at x may be found by linear interpolation.. In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.

  5. Fixed point (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Fixed_point_(mathematics)

    The function () = + (shown in red) has the fixed points 0, 1, and 2.. In mathematics, a fixed point (sometimes shortened to fixpoint), also known as an invariant point, is a value that does not change under a given transformation.

  6. Time series - Wikipedia

    en.wikipedia.org/wiki/Time_series

    Panel data is the general class, a multidimensional data set, whereas a time series data set is a one-dimensional panel (as is a cross-sectional dataset). A data set may exhibit characteristics of both panel data and time series data. One way to tell is to ask what makes one data record unique from the other records.

  7. MATLAB - Wikipedia

    en.wikipedia.org/wiki/MATLAB

    MATLAB (an abbreviation of "MATrix LABoratory" [18]) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks.MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.

  8. Closest pair of points problem - Wikipedia

    en.wikipedia.org/wiki/Closest_pair_of_points_problem

    The closest pair of points problem or closest pair problem is a problem of computational geometry: given points in metric space, find a pair of points with the smallest distance between them. The closest pair problem for points in the Euclidean plane [ 1 ] was among the first geometric problems that were treated at the origins of the systematic ...

  9. Level-set method - Wikipedia

    en.wikipedia.org/wiki/Level-set_method

    Below it, the red surface is the graph of a level set function determining this shape, and the flat blue region represents the X-Y plane. The boundary of the shape is then the zero-level set of φ {\displaystyle \varphi } , while the shape itself is the set of points in the plane for which φ {\displaystyle \varphi } is positive (interior of ...
