enum vDiscrete cosine transform types.
Discrete Cosine Transforms
The functions in the Discrete Cosine Transforms (DCT) family calculate a discrete cosine transform of a specified length on a vector.
func vCreates a data structure for use with v to perform a single-precision, discrete cosine transform.
func vCalculates the discrete single-precision cosine transform for a vector.
