Write a set of commands (a script) that will do the following:

(a) Generate one random integer between 1 and 1000 and assign it to the variable mynum (see built-in

command randi).

(b) Find the remainder when mynum is divided by 2 and assign it to the value myrem (see built-in command

rem).

(c) Using if-else statements and myrem, check and print out whether mynum is even or odd.

(You may use any display or print option of your choice.)

This is the script I have so far:

myrem = rem(number,2);

number = randi(1000);

my = myrem;

if my == 0

disp('Even');

elseif my == 1

disp('Odd');

and when I try to 'call' it my = myrem it reads back that it is " Unrecognized function or variable 'myrem'. " Could anyone help me figure why my script won't work?

在 MATLAB Online 中打开

number = randi(1000);%use must generate the number first before using it
myrem = rem(number,2);
%my = myrem; no need for this
if myrem == 0
        disp('Even');
else%if my == 1 only two possibilities
        disp('Odd');
end%don't forget to end
