4.1 Exercises
In Exercises 1-6, first enter the following
vectors.
>> v=[1,3,5,7], w=[5,2,5,4]
v =
1 3 5 7
w =
5 2 5 4
In each exercise, first predict the output
of the given command, then validate
your response with the appropriate
Matlab command. Note: The
idea here is not to simply enter the
command. Rather, spend some time
thinking, then predict the output before
you enter the command to verify
your conclusion.
