  2. Matplotlib - Wikipedia

    en.wikipedia.org/wiki/Matplotlib

    Matplotlib-animation [11] capabilities are intended for visualizing how certain data changes. However, one can use the functionality in any way required. These animations are defined as a function of frame number (or time). In other words, one defines a function that takes a frame number as input and defines/updates the matplotlib-figure based ...

  3. Connected-component labeling - Wikipedia

    en.wikipedia.org/wiki/Connected-component_labeling

    Union-find essentially stores labels which correspond to the same blob in a disjoint-set data structure, making it easy to remember the equivalence of two labels by the use of an interface method E.g.: findSet(l). findSet(l) returns the minimum label value that is equivalent to the function argument 'l'.

  4. Euler diagram - Wikipedia

    en.wikipedia.org/wiki/Euler_diagram

    By use of the adjacency of "1"s in the Karnaugh map (indicated by the grey ovals around terms 0 and 1 and around terms 2 and 6) one can "reduce" the example's Boolean equation i.e. (x'y'z' + x'y'z) + (x'yz' + xyz') to just two terms: x'y' + yz'. But the means for deducing the notion that "No X is Z", and just how the reduction relates to this ...

  5. Sigma bond - Wikipedia

    en.wikipedia.org/wiki/Sigma_bond

    In chemistry, sigma bonds (σ bonds) or sigma overlap are the strongest type of covalent chemical bond. [1] They are formed by head-on overlapping between atomic orbitals along the internuclear axis. Sigma bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups. In this formal approach, a σ-bond is ...

  6. Gram matrix - Wikipedia

    en.wikipedia.org/wiki/Gram_matrix

    In quantum chemistry, the Gram matrix of a set of basis vectors is the overlap matrix. In control theory (or more generally systems theory ), the controllability Gramian and observability Gramian determine properties of a linear system.

  7. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    Overlap between the H 1s and F 2p z orbitals is also symmetry allowed, and these two atomic orbitals have a small energy separation. Thus, they interact, leading to creation of σ and σ* MOs and a molecule with a bond order of 1. Since HF is a non-centrosymmetric molecule, the symmetry labels g and u do not apply to its molecular orbitals. [23]

  8. Scree plot - Wikipedia

    en.wikipedia.org/wiki/Scree_plot

    A sample scree plot produced in R.The Kaiser criterion is shown in red.. In multivariate statistics, a scree plot is a line plot of the eigenvalues of factors or principal components in an analysis. [1]
