Matlab’s Debugger

Return to List of Lectures

Previous Lecture

• Questions?
  • Writing “factorial” function for lab
    • Do not use Matlab’s built-in factorial function!
• Debugger
  • “Matlab Debugging Tutorial”
    • Debugging = finding out why code doesn’t work
    • Breakpoints let you narrow in on problem
    • Step command to do single steps
    • Can copy and paste code into command window to narrow in on problem
    • Conditional breakpoints let you stop only if some test is true
  • Examples
    • Absolute value and branches
      • Set breakpoint early in function, typically on first line, use “step” to see how function executes from there
    • Stick person functions and “step in,” “step out”
      • “Step in,” “step out” useful for looking inside a function called from another
• Branching Lab
• Next
  • “While” loops
  • Read sections 13.1 - 13.3
