MATLAB for Engineering Students: Solve Problems, Plot Data, and Build Simple Models
暫譯: 工程學生的 MATLAB：解決問題、繪製數據與建立簡單模型

Do you want to use MATLAB for engineering calculations, data analysis, plotting, and modeling without feeling lost in isolated commands?

MATLAB for Engineering Students is a practical, beginner-friendly guide to using MATLAB as an engineering problem-solving tool. Written for engineering students, technical learners, career switchers, and working professionals, this book teaches MATLAB through calculations, plots, data workflows, reusable functions, numerical methods, and simple models.

You will begin by learning how engineers move from a question to a calculation, from measurements to a plot, and from an equation to a model that can be checked. From there, each chapter develops MATLAB skills through practical engineering examples drawn from mechanical, electrical, thermal, fluid, structural, environmental, and measurement problems.

Instead of treating MATLAB as only a calculator, this book shows how to use it as a repeatable engineering workflow: define the problem, identify known values, state assumptions, select equations, plan the computation, implement the solution, inspect the results, validate the results, and communicate the findings.

Inside this practical guide, you will learn how to:

- Understand MATLAB as a calculator, programming language, and modeling environment
- Use MATLAB for engineering calculation, visualization, algorithm development, and numerical modeling
- Define inputs, outputs, parameters, assumptions, and units before writing code
- Translate equations into algorithms
- Estimate mechanical work and power
- Calculate electrical energy consumption
- Check numerical output using engineering judgment
- Use hand estimates, limiting cases, physical expectations, and unit checks
- Access MATLAB through desktop MATLAB or MATLAB Online
- Understand the MATLAB interface
- Use the Command Window, Workspace, Current Folder, Editor, Live Editor, Command History, and figures
- Enter commands and create variables

The book uses core MATLAB so learners can develop transferable skills without depending on specialist toolboxes. Arrays, matrices, tables, plotting, scripts, functions, numerical methods, and ordinary differential equations provide a strong foundation for later work in signals, control systems, optimization, Simulink, and larger engineering projects.

The examples are practical and engineering-centered. You will work with mechanical work, electrical energy, fluid pressure, stress, heat loss, temperature sensors, safe operating conditions, materials testing, environmental measurements, tensile-test data, sensor logs, beam deflection, flow regimes, fluid-flow functions, linear systems, resistor networks, force balance, pipe operating points, measured power data, sensor calibration, insulation selection, cooling, tank drainage, mass-spring motion, and thermal-response modeling.

This book also teaches engineering judgment from the beginning. You will learn to attach units to variable names, keep assumptions visible, check limiting cases, compare results with hand estimates, preserve original measurements, separate inputs from calculation logic, avoid trusting output blindly, and report numerical results with appropriate precision.

Whether you are an engineering student, technical learner, career switcher, laboratory learner, working professional, or self-taught reader who needs MATLAB for calculations, plots, data handling, and simple models, this book gives you a structured path into practical computational engineering.

Stop treating MATLAB output as an answer by itself. Learn how to solve engineering problems, plot and communicate data, build reusable calculations, check numerical results, and create simple validated models with confidence.
