Do the part b of the attached question

Transcribed Image Text:Write a MATLAB function
that takes a number as an input argument and
checks to see if the number is lucky. In the function, begin by defining a vector named secretLucky
with the values 19, 22, 5, 9, 11, 15, 21. These are secret lucky numbers.
Use a for-loop in the function to check, element-by-element, if the number passed in to the function is
in the secretLucky vector. If the number is found in secretLucky, return true (1). If the number is
not found in secretLucky, return false (0). Include help comments in the function.
Your testLucky function must behave as shown below: (user input is underlined)
>> help testLucky
testLucky(x) - determine whether x is a lucky number
return true (1) if x is a lucky number
return false (0) if x is not a lucky number
>> testLucky(5)
ans =
logical
1
>> testLucky(6)
ans =
logical
Hint: To get a logical 1 and logical 0 as output of your function, see "help true" and "help false".
1b:
Write a MATLAB program
that prompts the user to enter a number in the range 0
to 25. If the number entered is less than 0 or greater than 25, output an out-of-range message and
terminate. If the number entered is in the required range, proceed to test the number using the
testLucky function written in the last question. Inform the user if the number entered is lucky or not
lucky.
Three example runs of the program are shown below, with user input underlined. Your program
should create output exactly as shown below for the three values entered. Of course, your program
should accept any number as input.
Enter an number in the range 0 to 25: 22
You win! 22 is a lucky number
>>
Enter an number in the range 0 to 25: 10
Sorry! 10 is not a lucky number
>>
Enter an number in the range 0 to 25: 33
Number out of range!
>>
