Error functions

In the following section, we will learn about the error functions.

Getting ready...

Install the proper library, according to the function used.

How to do it...

Error functions are used as follows:

Install the proper function
Execute the function
Solve the function
The result will be presented

Here we have the functions and their description:

Function	Description
`erf(z)`	Returns the error function of complex argument
`erfc(x)`	Complementary error function, 1 - erf(x)
`erfcx(x)`	Scaled complementary error function, exp(x2) erfc(x)*
`erfi(z)`	Imaginary error function, -i erf(i z)
`erfinv(y)`	Inverse function for `erf`
`erfcinv(y)`	Inverse function for `erfc`
`wofz(z)`	Faddeeva function
`dawsn(x)`	Dawson's integral
`fresnel(z)`	Fresnel `sin` and `cos` integrals
`fresnel_zeros(nt)`	Compute `nt` complex zeros of sine and cosine Fresnel integrals `S(z)` and `C(z)`
`modfresnelp(x)`	Modified Fresnel positive integrals
`modfresnelm(x)`	Modified Fresnel negative integrals

The following are not universal functions.
