ERF(a,b,accuracy)


  • is the lower limit and is the upper limit.
  • gives accurate value of the solution

Description

  • This function gives the value of the error function .
  • Error function is the special function which is encountered in integrating the normal distribution.
  • In , is the lower limit of the integrating function and is the upper limit of the integrating function.
  • Also is optional. When we are omitting the value, then the integral of the error function between 0 and the given value is returned otherwise it will consider the given and values.
  • This function is also called Gauss error function.
  • is defined by:
  • .
  • In this case is the lower limit and is the upper limit.
  • This function will return the result as error when
1.any one of the argument is non-numeric.
2. or  is negative.

ZOS

  • The syntax is to calculate error function in ZOS is .
    • is the lower limit and is the upper limit.
    • gives accurate value of the solution.
  • For e.g.,erf(2,3),erf(2,3,0.001)

Examples

  1. ERF(1,2)=0.15262153
  2. ERF(3,2)=-0.004655645
  3. ERF(0,1)=0.842700735
  4. ERF(5)=1
  5. ERF(-3)=NAN
