editThe Haar Transform, or the **Haar Wavelet Transform** (HWT) is one of a group of related transforms known as the **Discrete Wavelet Transforms** (DWT). DWT Transforms, and the Haar transform in particular can frequently be made very fast using matrix calculations. The fastest known algorithm for computing the HWT is known as the **Fast Haar Transform**, and is comparable in speed and properties to the Fast Fourier Transform.

## Uses of the Haar Transform

editHaar transform uses non-sinusoidal basic wavefunction. So it has great applications related to DSP. The basic haar transform matrix is defined by the function Hk(x). Where o<=k<=N-1, N is the matrix size.
