Density matrix - Wikipedia
wikipedia.org

https://en.wikipedia.org/wiki/Density_matrix

The density matrix is obtained from the density operator by choice of basis in the underlying space. In practice, the terms density matrix and density operator are often used interchangeably. In operator language, a density operator for a system is a positive semi-definite , Hermitian operator of trace one acting on the Hilbert space of the system.

https://en.wikipedia.org/wiki/Matrix_(mathematics)

is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a "2×3-matrix", or a matrix of dimension 2×3.Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra.Therefore, the study of matrices is a large part of linear algebra, and most properties and operations of abstract linear algebra can …

Density - Wikipedia
wikipedia.org

https://en.wikipedia.org/wiki/Density

Density (volumetric mass density or specific mass), is the substance's mass per unit of volume.The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: = where ρ is the density, m is the mass, and V is the volume. In some cases (for …

https://en.wikipedia.org/wiki/Multivariate_kernel_density_estimation

Kernel density estimation is a nonparametric technique for density estimation i.e., estimation of probability density functions, which is one of the fundamental questions in statistics.It can be viewed as a generalisation of histogram density estimation with improved statistical properties. Apart from histograms, other types of density estimators include parametric, spline, wavelet …

Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts. As described above, many physical processes are best described as a sum of many individual frequency components. Any process that quantifies the various amounts (e.g. amplitudes, …

https://en.wikipedia.org/wiki/Pixel

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.. Each pixel is a sample of an original image; more samples typically provide more accurate …
