A.6 Programming

The if-else statement can be demonstrated through the following example.

>> for i = 1:6

x = rand(1);

if x<0.5

disp('x is less than 0.5')

else

disp('x is greater than 0.5')

end

end

Note that the rst end is the end of the if statement and the second end

is the end of the for loop. Note that when a semicolon is put at the end of

a statement, it suppresses printing of the variable. The following output is

displayed by running the above code.

x is greater than 0.5

x is greater than 0.5

x is less than 0.5

x is greater than 0.5

x is greater than 0.5

x is less than 0.5
