    Microsoft Excel has the basic features of all spreadsheets, [11] using a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering, and financial needs.

  3. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    Functions involving two or more variables require multidimensional array indexing techniques. The latter case may thus employ a two-dimensional array of power[x][y] to replace a function to calculate x y for a limited range of x and y values. Functions that have more than one result may be implemented with lookup tables that are arrays of ...

    This part of the line display process is the Horizontal Blank. [1] [2] In detail, the Horizontal blanking interval consists of: front porch – blank while still moving right, past the end of the scanline, sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black". back porch – blank while moving right again ...

    In scientific literature, one occasionally encounters the term scotopic lux which corresponds to photopic lux, but uses instead the scotopic visibility weighting function. [10] The scotopic luminosity function is a standard function established by the Commission Internationale de l'Éclairage (CIE) and standardized in collaboration with the ISO ...

  7. Retina horizontal cell - Wikipedia

    en.wikipedia.org/wiki/Retina_horizontal_cell

    Horizontal cells span across photoreceptors and summate inputs before synapsing onto photoreceptor cells. [1] [2] Horizontal cells may also synapse onto bipolar cells, but this remains uncertain. [1] [4] There is a greater density of horizontal cells towards the central region of the retina.

  8. Retina bipolar cell - Wikipedia

    en.wikipedia.org/wiki/Retina_bipolar_cell

    Bipolar cells effectively transfer information from rods and cones to ganglion cells. The horizontal cells and the amacrine cells complicate matters somewhat. The horizontal cells introduce lateral inhibition to the dendrites and give rise to the center-surround inhibition which is apparent in retinal receptive fields.

  9. Data transformation (statistics) - Wikipedia

    In the lower plot, both the area and population data have been transformed using the logarithm function. In statistics, data transformation is the application of a deterministic mathematical function to each point in a data set—that is, each data point z i is replaced with the transformed value y i = f(z i), where f is a function.
