# quadrature_function_array

## Declaration

```swift
typealias quadrature_function_array = (UnsafeMutableRawPointer?, Int, UnsafePointer<Double>, UnsafeMutablePointer<Double>) -> Void
```

## Parameters

- `arg`: User argument passed back to the function when evaluated
- `n`: Dimension of arrays X and Y
- `x`: Array of points to evaluate the function
- `y`: Array receiving the values

## Discussion

Discussion Y=F(X) one-dimensional real function, array form, double precision Should set values y[i] = F(x[i]) for i=0..n-1.
