    Functions in 2D and 3D

    Functions of the form F(x) and F(x,y) containing up to 20 subfunctions, 30 special functions, 150 numerical and 100 named constants.

    Special Functions

    Special Functions (real numbers only!)

    Random numbers

    Modulo function

    Fresnel integrals:

    Exponential integrals and related functions

    Gamma function and related functions

    Riemann Zeta function

    Bessel functions

    Elliptic integrals

    Airy functions

    Probability function

    Distribution functions

    Special functions: Random numbers
    Random numbers: Random(a), Randstep(a,x)

    • Random numbers:  Random(a)
                  Random(a) Generates a series of random numbers
    between 0 and 1 from seed a. Below an example is given
    F1=Random(0.5) calculated
    for 100 x-values (F is not a function of x here)


    • Random steps with probability x: Ranstep(a,x)
                  Generates a random series of  0's and 1's from seed a.
    The average fraction (or probablity) of 1's is given by x.
    Below an example is given of an Iteration (100 iterations):
    F2=F1+ Ranstep(0.5,0.3)
