Mod
(Built-in Mathematica Symbol) Mod[m, n] gives the remainder on division of m by n. Mod[m, n, d] uses an offset d.
Multinomial[n_1, n_2, ...] gives the multinomial coefficient (n_1 + n_2 + ...)!/(n_1! n_2! ...).
QBinomial[n, m, q] gives the q-binomial coefficient (n; m)_q.
TransferFunctionCancel[tf] cancels common poles and zeros in the TransferFunctionModel object tf.TransferFunctionCancel[tf, crit] cancels only common pole-zero pairs e_i for ...
Exp
(Built-in Mathematica Symbol) Exp[z] gives the exponential of z.
InterpolateRoot[lhs == rhs, {x, x_0, x_1}] searches for a numerical solution to the equation lhs == rhs using x_0 and x_1 as the first two values of x.
AiryAi
(Built-in Mathematica Symbol) AiryAi[z] gives the Airy function Ai(z).
AiryBi
(Built-in Mathematica Symbol) AiryBi[z] gives the Airy function Bi(z).
ArcCos
(Built-in Mathematica Symbol) ArcCos[z] gives the arc cosine cos -1 (z) of the complex number z.
