  2. Class information • Textbook • Hanselman & Littlefield, “Mastering Matlab 7”, Prentice Hall, Upper Saddle River, NJ, 2005.

  3. Example on Page 6 • Variable • Keyword (reserved word) • ; • Calculation • % (comment) • , • error

  4. <File> <new> • Or the direct access from the icon “blank”

  5. Input / Output • Parameter input • Page 33

  6. Xls input (the easiest one) • Sample xls input file • Page 250 • Also available at http://www.mathworks.com/access/helpdesk/help/techdoc/ref/xlsread.html

  7. Something must know • Page 39 • How to use the readout n?

  8. Apply an operation on every unit in the array • Page 47 • ` (especially useful to handle different input format, see the discussion later)

  9. Standard arrays, page 54 • Ones, zeros, size, eye, rand, randn, diag • Repmat(pi, 3, 4)

  10. Array sorting, search, page 73

  11. Find(a>4, 2, ‘first’) • Page 189, such as a filter to discard NaN or InF • Max • Min • Size

  12. Manipulation * , page 82 (optional)

  13. Multidimensional array • 1-d => 2-d => 3-d, page 98 • 3-d => 2-d => 1-d, page 99 • Reshape(page 57), cat(page 101), flipdim, shiftdim, permute • Their search and sorting, such as a 3d array sorted in one dimension.
