A Gaussian function is the wave function of the ground state of the quantum harmonic oscillator. The molecular orbitals used in computational chemistry can be linear combinations of Gaussian functions called Gaussian orbitals (see also basis set (chemistry)). Se mer In mathematics, a Gaussian function, often simply referred to as a Gaussian, is a function of the base form Gaussian functions are often used to represent the probability density function of a Se mer Gaussian functions arise by composing the exponential function with a concave quadratic function: • Se mer A number of fields such as stellar photometry, Gaussian beam characterization, and emission/absorption line spectroscopy work with sampled Gaussian functions … Se mer Gaussian functions appear in many contexts in the natural sciences, the social sciences, mathematics, and engineering. Some examples include: • In statistics and probability theory, Gaussian functions appear as the density function of the Se mer Base form: In two dimensions, the power to which e is raised in the Gaussian function is any negative-definite quadratic form. Consequently, the level sets of the Gaussian will always be ellipses. A particular example … Se mer One may ask for a discrete analog to the Gaussian; this is necessary in discrete applications, particularly digital signal processing.
