Example output

The figure below shows Figure 3 from the article, showing time series of the x, y and z variables of the Lorenz system (top row), the corresponding phase space embeddings along with the Lorenz attractor (middle row). The bottom row shows a comparison of recurrence plots based on unidimensional recurrence quantification analysis (RQA) to multidimensional Recurrence Quantification Analysis (MdRQA).
