    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):
    F1=F2
    F2=F1+ Ranstep(0.5,0.3)
