MATLAB Colormaps play a vital role for engineers and researchers in data visualisation, aiding in the effective representation and interpretation of their data. Users must have a comprehensive understanding of Colormaps to create visually appealing and informative plots. Colormaps are an essential component of data visualisation that help in conveying information effectively. In simple terms, a Colormap is a mapping between numerical values and colors. It assigns a unique color to each value or range of values in a dataset, allowing for a visual representation of the data's characteristics. The primary purpose of Colormaps is to enhance the understanding and interpretation of data.
