erfi
erfi(x)
Compute the imaginary error function of x,
defined by $-i \operatorname{erf}(ix)$.
Examples
-
Calculate the imaginary error function for a real number:
julia> erfi(2.5) 0.7457231257628999This example computes the imaginary error function for the real number 2.5.
-
Evaluate the imaginary error function for a complex number:
julia> erfi(1 + 2im) 1.3161512816979478 + 0.482287973162673jIt calculates the imaginary error function for the complex number
1 + 2im. - Use the imaginary error function in an expression:
julia> result = 2 * erfi(0.5) + erfi(1.5) - erfi(2.0) 0.2800658901948452Here, the imaginary error function is used within an expression to compute the result.
Common mistake example:
julia> erfi("hello")
ERROR: MethodError: no method matching erfi(::String)In this example, the input provided is not a valid argument for the erfi function. The function expects a numeric value as an argument. Make sure to pass a valid numeric input to the erfi function to avoid such errors.
