Mathematical Constants and Functions

Summary:

In MuPAD, at the beginning of a session the following mathematical constants
and functions are defined:

 PI          --   pi (3.14159 ...)
 E           --   e (2.71828 ...)
 EULER       --   Euler constant (0.57721 ...)
 I           --   imaginary unit

 infinity    --   infinity
 abs         --   absolute value of a numerical argument
 bernoulli   --   Bernoulli numbers and polynomials
 binomial    --   binomial coefficients
 eint        --   exponential integral
 erf         --   error function
 erfc        --   complementary error function
 exp         --   exponential function
 fact        --   factorial function fact(n) = n!
 gamma       --   gamma function
 igamma      --   incomplete gamma function
 ln          --   natural logarithm (base e)
 psi         --   digamma function
 sign        --   sign of a numerical argument
 sqrt        --   square root of a numerical argument
 zeta        --   zeta function

Furthermore, the trigonometric and hyperbolic functions

     cos, cot, csc, sec, sin, tan,
     cosh, coth, csch, sech, sinh, tanh

as well as their inverse functions

     acos, acot, acsc, asec, asin, atan,
     acosh, acoth, acsch, asech, asinh, atanh

are defined.

If the argument cannot be simplified the functions return the function call
with the evaluated argument.
