When calling a function in a script, I keep getting the same "Undefined function or variable 'input3'". The function is described below :
function results = f(input1,input2, input3, input4)
....
...
Later on in function, I use input3 and get the error message "Undefined function or variable 'input3'". I checked the function, script and everything and there are no typos. I don't understand how matlab is not recognizing the variable when it is clearly an input into the function. Help would be appreciated.

input1 =1;
input2 = 2;
input3 = 3;
input4 = 4;
results = f(input1,input2, input3, input4) % this is how you call a function, assuming that the function is saved in a file called “f.m” if you’re using versions before 2016b

Show how your calling the function and the value of input3 using a screenshot.

Does madsen_plot_ROC have an evalin('caller') or assignin('caller') in it?
If not then copy the madsen_plotROC portion of the call from two lines above, pasting it over the call on that line. We know the line two above worked because we had to get through it to get to the (3,2,4) plot. Doing the copy/paste would remove the possibility of an invisible typing mistake that is not obvious due to the font.
