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: ')

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.
Regards,
Sriram
