Re: Built-in function for `switch'

[Guido Dietz]

Puhh, very promt implementation of switch. Your support is better than any
commercial one!

Seems so, look below ...

No, but the second occurence will have no effect :-), see below ...

Hmm, I will test it ...

newline

"Any number of case groups" is allowed, I 'll test the zero ...

They say:
switch *expression* (scalar or string)
  case value1
        *statements*
  case value2
        *statements*
  .
  .
  .
  otherwise
        *statements*
end

o The word swtitch followed by a scaler or string expression to evaluate.
o A case group consists of the word case followed by a possible value for
  expression, all on a single line! switch executes the following statements
  until MATLAB encounters the next case statement or the otherwise statement.
  Only the first matching case is executed!

        Your home electrical system is basically a bunch of wires that
bring electricity into your home and take if back out before it has a
chance to kill you.  This is called a "circuit".  The most common home
electrical problem is when the circuit is broken by a "circuit
breaker"; this causes the electricity to back up in one of the wires
until it bursts out of an outlet in the form of sparks, which can
damage your carpet.  The best way to avoid broken circuits is to change
your fuses regularly.
        Another common problem is that the lights flicker.  This
sometimes means that your electrical system is inadequate, but more
often it means that your home is possessed by demons, in which case
you'll need to get a caulking gun and some caulking.  If you're not
sure whether your house is possessed, see "The Amityville Horror", a
fine documentary film based on an actual book.  Or call in a licensed
electrician, who is trained to spot the signs of demonic possession,
such as blood coming down the stairs, enormous cats on the dinette
table, etc.
