gamma Description

 The names Γ and γ may refer to any of several distinct quantities or operations.
 • For the number 0.577215... (Euler's constant), see gamma.
 • For the Gamma function, see GAMMA.
 • For the Gamma distribution in statistics, see Statistics[Distributions][Gamma].
 • For adjusting the gamma of an image, see ImageTools[Gamma].
 • For the Dirac gamma matrices, see Physics[Dgamma].
 • For the Gamma process in finance, see Finance[GammaProcess].
 • For the risk measure Gamma under the Black-Scholes model, see Finance[BlackScholesGamma].
 • For the Digamma and Polygamma functions, see Psi. Examples
