Rules
(Mathematica Guide) Everything that Mathematica does can be thought of as derived from its ability to apply general transformation rules to arbitrary symbolic expressions. The Mathematica ...
Rules are a key part of Mathematica 's powerful expression transformation language. These "How tos" give step-by-step instructions for using rules in Mathematica .
$TimeUnit gives the minimum time interval in seconds recorded on your computer system.
BinormalDistribution[{\[Mu]_1, \[Mu]_2}, {\[Sigma]_1, \[Sigma]_\ 2}, \[Rho]] represents a bivariate normal distribution with mean {\[Mu]_1, \[Mu]_2} and covariance matrix ...
Divisible[n, m] yields True if n is divisible by m, and yields False if it is not.
