Erf
(Built-in Mathematica Symbol) Erf[z] gives the error function erf(z). Erf[z_0, z_1] gives the generalized error function erf(z_1) - erf(z_0).
ErlangDistribution[k, \[Lambda]] represents the Erlang distribution with shape parameter k and rate \[Lambda].
Erosion
(Built-in Mathematica Symbol) Erosion[image, ker] gives the morphological erosion of image with respect to the structuring element ker.Erosion[image, r] gives the erosion with respect to a range-r square.
ErrorBox[boxes] is a low-level box construct that represents boxes that cannot be interpreted in input or output.
ErrorBoxOptions -> {opt_1 -> val_1, opt_2 -> val_2, ...} applies options and corresponding values.
EstimatedDistribution[data, dist] estimates the parametric distribution dist from data.EstimatedDistribution[data, dist, {{p, p_0}, {q, q_0}, ...}] estimates the parameters ...
EstimatorGains[ss, {p_1, p_2, ..., p_n}] gives the estimator gain matrix for the StateSpaceModel object ss, such that the poles of the estimator are p_i.
EstimatorRegulator[ss, {l, \[Kappa]}] constructs the feedback regulator for the StateSpaceModel object ss with estimator and feedback gain matrices l and \[Kappa], ...
EuclideanDistance[u, v] gives the Euclidean distance between vectors u and v.
EulerE
(Built-in Mathematica Symbol) EulerE[n] gives the Euler number E_n. EulerE[n, x] gives the Euler polynomial E_n (x).
