Hartley Transform
The Discrete Hartley Transform returns the transformed array, a real array having the same number of elements as the input.
• dht(v)—Returns the Hartley transform of the vector v.
• idht(v)—Returns the inverse Hartley transform of the vector v.
The Hartley transform is designed to contain the information inherent to the Fourier transform but to avoid entering the complex domain.
Arguments
• v is a vector or matrix of real-valued data.
