MATLAB (an abbreviation of "MATrix LABoratory" [22]) 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.
The scattered points are the input scores of observations and the arrows show the contribution of each feature to the input loading vectors. Spectramap biplot of Anderson's iris data set Discriminant analysis biplot of Fisher's iris data. Biplots are a type of exploratory graph used in statistics, a generalization of the simple two-variable ...
enum.inject(&block) enum.reduce(&block) enum.reverse_each.inject(&block) enum.reverse_each.reduce(&block) In Ruby 1.8.7+, can also pass a symbol representing a function instead of a block. enum is an Enumeration Please notice that these implementations of right folds are wrong for non-commutative &block (also initial value is put on wrong side ...
Composite image showing JPG and PNG image compression. Left side of the image is from a JPEG image, showing lossy artefacts; the right side is from a PNG image. In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. [14]
A permutation matrix is a (0, 1)-matrix, all of whose columns and rows each have exactly one nonzero element.. A Costas array is a special case of a permutation matrix.; An incidence matrix in combinatorics and finite geometry has ones to indicate incidence between points (or vertices) and lines of a geometry, blocks of a block design, or edges of a graph.
A binary digit can have one of two possible values, and may be physically represented with a two-state device. These state values are most commonly represented as either a 0 or 1. [30] bit rate (R) Also bitrate. In telecommunications and computing, the number of bits that are conveyed or processed per unit of time. [31] blacklist. Also block list.
Graphs of functions commonly used in the analysis of algorithms, showing the number of operations versus input size for each function. The following tables list the computational complexity of various algorithms for common mathematical operations.
A block diagram of a PID controller in a feedback loop, where r(t) is the desired process value or "set point", and y(t) is the measured process value A proportional–integral–derivative controller (PID controller) is a control loop feedback mechanism ( controller ) widely used in industrial control systems .
