data WeberResult = WeberResult {
- _result :: Complex Double
- _errors :: (Double, Double)
- _codes :: (Int, Int)
}
weberE :: Complex Double -> Complex Double -> Double -> Int -> IO WeberResult

Documentation

data WeberResult Source #

Data type to store the result of a computation of the Weber E-function. The fields are _result for the value, _errors for the error estimates of the integrals used for the computation, and _codes for the convergence codes of these integrals (0 for success).

Arguments

:: Complex Double	order, complex number
-> Complex Double	the variable, a complex number
-> Double	target relative accuracy for the integrals, e.g. 1e-5
-> Int	number of subdivisions for the integrals, e.g. 5000
-> IO WeberResult	result

Weber-E function. It is computed with two integrals. The field _errors in the result provides the error estimates of the integrals. The field _codes provides the codes indicating success (0) or failure of each integral.
