Problem with script use

Hi,

I got a problem of using a script. Normally, when I can create a function in a script, I can apply the function in the command window. But I am now assigned a homework that asking me to do a live script. It means that I have to create some options on the script and the user will input one of those options

For example :

Option 1 : blue

Option 2 : red

Option 3 : yellow

Enter your choice:

Notice that If i enter my choice which is 1 (blue). It will return blue color.

I know how to input matlab code imread and imshow to show the picture of blue color but will I use if function at the end of the script or on each line after the option??

How can I create a script like that? I don't know how to explain it correctly since I am a English beginner. If you want further information to understand my idea, please tell me.

Here is my trial and I was confused how can I enter my choice when a run a script.? Please give me some references to understand how to run this code.

display('Hello User!!')
display('Option 1: Flip the picture  !!') 
display('Option 2: Get back to 1900s by grayscaling !!') 
display('Option 3: Complementing the picture !!')          
display('Option 4: Rotating the image to 90 degree')
display('Option 5: Rotating the image to 90 degree')
display('Enter a valid choice: ')

If i understood you correctly you need switch operator

switch n
    case 1
        color = blue;
    case 2
        color = red;
end

See more switch

hi, thanks for your response. I understand your code but where is the n go? I haven't assigned any "n" and where should i assgined them? I guess the "n" should be assigned in the last line " Enter a valid choice" right?

Try

n = input('Enter a valid choice: '); % rather than display here

Look more details about input function.

Hope this helps.

Hi David,

To enter a choice when run a script, you can use input function.

Try

n = input('Enter a valid choice: ');
% Then perform the different operations based on the value of n, through switch or if-else statements

For more details, look at the input documentation page.

Hope this helps.
