Function

# vvcosisin

Calculates the cosine and sine of each element in an array of double-precision values.

## Parameters

`parameter 1`

The output array, y.

`parameter 2`

The input array, x.

`parameter 3`

The number of elements in the arrays.

## Discussion

This function calculates the complex number on the unit circle corresponding to the angle given by each element of a vector.

The following code shows an example of using `vvcosisin`.

On return, for each array element in `y`, `real` is the cosine of `x` and `imag` is the sine of x.
