Help

• Information about specific MATLAB commands may obtained with the help command.
  • Simply typing help by itself actually produces a listing of the available MATLAB "toolboxes" (groupings of related commands and functions).
  • If you have any question about MATLAB commands, ask to MATLAB first as

    >>help
    >>help cos
    >>help sqrt
    >>help format
    >>help det
    >>help sym/det.m
    

• Give the command help chop and examine the output. Next, give, in sequence, the commands

  chop( 27.321592 , 5 )
  chop( 27.321592 , 4 )
  chop( 27.321592 , 3 )
  

  What is the use of chop (built-in) function. Are the answers what you expected?
