copysign(magnitudes:signs:result:)
Calculates each single-precision element in the magnitudes vector, setting its sign to the corresponding elements in the signs vector.
Declaration
static func copysign<T, U, V>(magnitudes: T, signs: U, result: inout V) where T : AccelerateBuffer, U : AccelerateBuffer, V : AccelerateMutableBuffer, T.Element == Float, U.Element == Float, V.Element == Float
