The need for matrix presentation by image is clear to all who in their work use high dimension matrices. Particular problem here make matrices that could not normally be presented by images – those whose elements are arbitrary real, or even complex numbers. Here we propose a solution for visualization of arbitrary, high dimension matrix. This is illustrated by several examples, with matrices used in two-dimensional discrete linear transforms, in image processing.
