  Before Getting Started… MATLAB: core program.  MATLAB Toolboxes: extended program  M-files (or p-files).  Simulink: GUI block diagram.  Simulink Blocksets: extended Simulink. Tonight: only (1) (75%) & (3) (25%).

  Outline • MATLAB – Mathematics – Graphics – Programming • Simulink – Graphic User Interface (GUI) block diagram modeling
• 5.
  Integrated Design Environment
• 6.
  Mathematics • Matrix-based representation
• 7.
  Mathematics Examples Ex1: Statetransition matrix Ex2: eigenvalue & singular value decomposition
• 8.
  Graphics • Basic graphiccommands: • Specialized plots & animation (make AVI movies): pie, histogram, contour plot, getframe, etc. • Graphic handles: get, set commands; gcf, gca. • Figure save, export, print, etc.
• 9.
  Graphic Examples Ex1: signal plot Ex2: image conversion
• 10.
  Programming • Data type(class): number (double), string (char), cell, logic, handle, etc. Function handle Ex. • Function handle: using @ or inline command • Script vs. Function • Array vs. For-loop
• 11.
  Programming Example (script)
• 12.
  Programming Example (function)
• 13.
  Simulink • Choosing asolver: continuous/discrete • Import/Export data • Configuration sets/parameters • Integrated with MATLAB workspace, M-files, C/C++  S- function • Advanced level: Stateflow, Real-Time Workshop, xPC Target
