The most recent version of PGPLOT is 5.2.2, released in February 2001, although third parties have written unofficial patches that include support for additional devices, 64 bit systems, and RGB (true color) plotting. PGPLOT provides C and Fortran 77 interface. There are also several user-contributed bindings, such as C++, perl, python, ruby ...
Bresenham's line algorithm. Bresenham's line algorithm is a line drawing algorithm that determines the points of an n -dimensional raster that should be selected in order to form a close approximation to a straight line between two points. It is commonly used to draw line primitives in a bitmap image (e.g. on a computer screen ), as it uses ...
Kernel density estimation of 100 normally distributed random numbers using different smoothing bandwidths.. In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights.
A turtle graphic pattern drawn with a Python program. The turtle has three attributes: a location, an orientation (or direction), and a pen. The pen, too, has attributes: color, width, and on/off state (also called down and up ). The turtle moves with commands that are relative to its own position, such as "move forward 10 spaces" and "turn ...
A confidence band is used in statistical analysis to represent the uncertainty in an estimate of a curve or function based on limited or noisy data. Similarly, a prediction band is used to represent the uncertainty about the value of a new data-point on the curve, but subject to noise. Confidence and prediction bands are often used as part of ...
An image along with its Y′, U, and V components respectively. Y′UV, also written YUV, is the color model found in the PAL analogue color TV standard (excluding PAL-N ). A color is described as a Y′ component ( luma) and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input ...
Euclidean sRGB. As most definitions of color difference are distances within a color space, the standard means of determining distances is the Euclidean distance.If one presently has an RGB (red, green, blue) tuple and wishes to find the color difference, computationally one of the easiest is to consider R, G, B linear dimensions defining the color space.
