The multidimensional system and signal theory forms the basis for various aspects of multimedia communication and for other applications. Frames, frames, and multi-camera views are multi-dimensional signals with two, three, and more dimensions.
Multi-dimensional systems describe the propagation of sound waves and electrical signals in power grids. But also the diffusion of matter particles and their chemical reactions are multi-dimensional processes. Finally, the vibrations of solids can be described by multidimensional systems.
