NormalDistribution[\[Mu], \[Sigma]] represents a normal (Gaussian) distribution with mean \[Mu] and standard deviation \[Sigma].NormalDistribution[] represents a normal ...
As discussed in "Exact and Approximate Results", Mathematica can handle approximate real numbers with any number of digits. In general, the precision of an approximate real ...
Length
(Built-in Mathematica Symbol) Length[expr] gives the number of elements in expr.
NMaxValue[f, x] gives the maximum value of f with respect to x.NMaxValue[f, {x, y, ...}] gives the maximum value of f with respect to x, y, .... NMaxValue[{f, cons}, {x, y, ...
NMinValue[f, x] gives the minimum value of f with respect to x.NMinValue[f, {x, y, ...}] gives the minimum value of f with respect to x, y, .... NMinValue[{f, cons}, {x, y, ...
Numerical sums, products and integrals. Here is a numerical approximation to ∑_(i=1)^∞((1)/(i^3)). NIntegrate can handle singularities in the integration region.
Much of what Mathematica does revolves around manipulating structured expressions. But you can also use Mathematica as a system for handling unstructured strings of text. ...
Part
(Built-in Mathematica Symbol) expr[[i]] or Part[expr, i] gives the i\[Null]^th part of expr. expr[[-i]] counts from the end. expr[[i, j, ...]] or Part[expr, i, j, ...] is equivalent to expr[[i]][[j]] .... ...
NArgMax
(Built-in Mathematica Symbol) NArgMax[f, x] gives a position x_max at which f is numerically maximized.NArgMax[f, {x, y, ...}] gives a position {x_max, y_max, ...} at which f is numerically ...
