Graphing with MATLAB

The relationship between calculations and graphics in computing was nearly nonexistent in the past, leaving computational users to rely solely on numerical listings to evaluate research outcomes. However, with significant technological advancements, researchers, engineers, and professionals from various domains can now easily integrate graphs into their work and research. The importance of incorporating graphs has been recognized throughout our educational journey, from basic to advanced levels, and this significance extends to various fields of knowledge, including biology, applied mathematics, and evolutionary computation. Graphs find direct application in scientific and technological works, aiding in analyzing research findings, mathematical evaluations, and presentations. Graphs have become an essential tool in research, as they provide a different perspective and facilitate evaluating research results. MATLAB stands out among the widely used software for generating high-quality and precise graphs due to its ability to produce visually striking graphs with just a few simple commands. In Sect. 2.1, a short introduction to the chapter is given. Section 2.2 describes the essential elements of graphing with MATLAB software. Section 2.3 presents the implementation of different commands to plot the contour of two-dimensional functions. Likewise, Sect. 2.4 reviews the most important features of MATLAB to create a triangular mesh. Section 2.5 gives an overview of the combined plots, and Sect. 2.6 The Mapping Toolbox is implemented in creating maps, manipulating satellite images, and creating a 3D globe.
