Automatically Entering Inputs into MATLAB Function

I have a function where I want to automatically add the input prompts since I already know the inputs needed.

EX: 12 for first line, 34 for 2nd line, 'abc' for 3rd line etc

I tried this solution out but it didn't work for me

@Emily - what is the signature for your function? Does it allow for input parameters or does the code have three lines that prompt the user to enter some data? You may want to post some of your code so that we can get an idea of what it looks like and so can recommend how to accomplish what you want.
