Study Notes

MATLAB Overview

MATLAB stands for MATrix LABoratory
Originally developed to provide easy access to matrix software from LINPACK and EISPACK projects

MATLAB Features

High-performance language for technical computing
Integrates computation, visualization, and programming environment
Sophisticated data structures
Built-in editing and debugging tools
Supports object-oriented programming

Advantages of MATLAB

Excellent tool for teaching and research
Advantages over conventional computer languages (e.g., C, FORTRAN) for solving technical problems
Interactive system with basic data element as an array, no dimension requirement

Process Overview

Development stages: System Conception, Analysis, Domain Analysis, System Design, Class Design, Implementation, Testing, Training, and Maintenance
Development life cycle: Waterfall Development and Iterative Development

System Conception

Conceive an application and formulate tentative requirements
Devising a system concept: New functionality, Streamlining, Simplification, Automation, Integration, Analogies, and Globalization
Elaborating a concept:
- Who is the application for? (Stakeholders)
- What problems will it solve? (Features)
- Where will it be used? (Compliment the existing base, locally, distributed, customer base)
- When is it needed? (Feasible time, required time)
- Why is it needed? (Business case)
- How will it work? (Brainstorm the feasibility of the problem)

Domain Analysis

Overview of analysis: Understanding the requirements by constructing models
Domain class model: Focuses on real-world things whose semantics the application captures
Domain state model: Focuses on the computer aspects of the application that are visible to users
Domain interaction model: Iterating the analysis

Development Stages

Analysis: Deeply understand the requirements by constructing models
System design: Devise the architecture and high-level strategy for solving the application problem
Class design: Determine the algorithms for realizing the operations
Implementation: Translate the design into programming code and database structures
Testing: Ensure that the application is suitable for actual use and satisfies requirements
Training: Help users master the new application
Maintenance: Preserve the long-term viability of the application

Waterfall Development

Requirements are very well known
Product definition is stable
Technology is understood
New version of an existing product
Phases: Requirement Gathering, Requirement Analysis, Design, Coding, Testing, Release, and Maintenance
Advantages:
- Easy to implement
- Helps to find errors earlier
- Easy to understand and use
- Works well when quality is more important than cost or schedule
- Documentation is produced at every stage
Disadvantages:
- Only suitable for small-size projects
- Constant testing of the design is needed
- Requirements may change
- Difficult to estimate time and cost for each stage
- Adjusting scope during the life cycle can kill a project
- High amount of risk and uncertainty
- Not suitable for handling dynamic changes in requirements

Iterative Development

Develope the nucleus of a system, then grow the scope of the system
Multiple iterations as the system evolves to the final deliverable
Each iteration includes: analysis, design, implementation, and testing

The ATM Case Study

Develop software for customers to access a bank's computers and carry out financial transactions without the mediation of a bank employee
Application is for: Vendor building the software
Problems it will solve: Serve both bank and user
Where it will be used: Locations throughout the world
When it is needed: Revenue
Why it is needed: Economic incentive
How it will work: N-tier architecture, 3-tier architecture
