  1. 1. MATLAB Presented By: Nathalie Tacconi Originally Prepared By: Sheridan Saint-Michel
  2. 2. What Is MATLAB? <ul><li>The name MATLAB is an abbreviation for MATrix LABoratory </li></ul><ul><li>MATLAB is an “interactive, matrix-based system for algorithm development, GUI Design, data analysis, data visualization, and numeric computation”. </li></ul>
  3. 3. What Is MATLAB? <ul><li>A way to solve complex numerical problems without actually writing a program </li></ul><ul><ul><li>Built-in tools </li></ul></ul><ul><ul><li>No program structuring </li></ul></ul><ul><li>MATLAB focuses on ease of use and quick development </li></ul>
  4. 4. Why Use MATLAB? <ul><li>Used mainly for algorithm development and data visualization </li></ul><ul><ul><li>Algorithms can be implemented and tested more quickly and easily than with traditional programming languages </li></ul></ul><ul><ul><li>Quickly get numerical and graphic answers to matrix and vector related math problems </li></ul></ul>
  5. 5. <ul><li>MATLAB is used for a wide range of applications including: </li></ul><ul><ul><li>Signal and Image Processing </li></ul></ul><ul><ul><li>Communications </li></ul></ul><ul><ul><li>Control Design </li></ul></ul><ul><ul><li>Testing and Analysis </li></ul></ul><ul><ul><li>Financial Modelling </li></ul></ul><ul><ul><li>Computational Biology </li></ul></ul>Why Use MATLAB?
  6. 6. Available Environments <ul><li>MATLAB is available in a number of environments including: </li></ul><ul><ul><li>PCs </li></ul></ul><ul><ul><li>Apple - Macintosh </li></ul></ul><ul><ul><li>Sun Workstations </li></ul></ul><ul><ul><li>VAX </li></ul></ul><ul><ul><li>MicroVAX </li></ul></ul>
  7. 7. The Basics <ul><li>MATLAB contains elaborate development tools to ease and speed development </li></ul><ul><li>MATLAB uses its own unique high-level language </li></ul><ul><li>Using MATLAB’s tools lets you write and test using much fewer lines of code than C or C++. </li></ul>
  8. 8. The Basics <ul><li>Starting Screen </li></ul>
  9. 9. Development Tools <ul><li>MATLAB editor - provides standard editing and debugging features, such as breakpoints and stepping through. </li></ul><ul><li>MATLAB profiler - records the time spent executing each line of code. </li></ul><ul><li>M-lint code checker - analyses your code and tells you where any problems are in addition to what changes can be made to make your program run faster. </li></ul>
  10. 10. Development Tools <ul><li>MATLAB editor </li></ul>
