This book combines the author’s years of experience in data analysis and scientific plotting to provide a detailed explanation of how MATLAB is used in creating technical charts and analyzing data. The book is divided into three parts comprising 12 chapters. Part 1 (Chapters 1-3) primarily covers the basics of MATLAB, including its operating environment, file operations, and program design. Part 2 (Chapters 4-8) delves into MATLAB’s data visualization capabilities, explaining details about figure windows, 2D plotting, 3D plotting, professional plotting, handle graphics objects, and other aspects of technical plotting. Part 3 (Chapters 9-12) focuses on descriptive data analysis, interpolation and fitting, regression analysis, optimization problem solving, and more.
