Multiwavelet toolbox for MATLAB
Jozef Kromka, Ondrej Kováč, Ján Šaliga · 2022
The Wavelet transform in the last decades gained a lot of popularity among researchers for its properties and abilities. The main subject of this article is the Multiwavelet transform. The Multiwavelet transform derivates from the Wavelet transform and has the same properties and abilities while providing additional properties and abilities, which the Wavelet transform cannot achieve. There exists a lot of freely available and easy-to-use tools to implement Wavelet transform. This cannot be said about the Multiwavelet transform. To overcome this problem and make the Multiwavelet transform more accessible in the signal processing field, the Multiwavelet toolbox for Matlab is proposed in the article. The article consists of two main parts. The first part is focused on Multiwavelet transform description and particularly on its convolution implementation. The second part describes the proposed toolbox and shows some examples of its use. The proposed toolbox consists of more than twenty-five original functions and scripts, and it is offered as GPL licensed software for scientific and educational purposes.
