vvcosisin(_:_:_:)
Calculates the cosine and sine of each element in an array of double-precision values.
Declaration
func vvcosisin(_: OpaquePointer, _: UnsafePointer<Double>, _: UnsafePointer<Int32>)Discussion
Parameters:
- parameter 1
The output array, y.
- parameter 2
The input array, x.
- parameter 3
The number of elements in the arrays.
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.
