I looked up the documentation for the input function, and when I copy and pasted an example, I get an error.
prompt = 'Do you want more? Y/N [Y]: ';
str = input(prompt,'s');
if isempty(str)
str = 'Y';
end
This code is in a brand new file called test.m, so those are the only 5 lines of code.
The error message is:
Index exceeds the number of array elements (9).
Error in test (line 2)
str = input(prompt);
I am in the latest version of matlab R2020a

You have a variable named input in the base workspace (assuming you're running this from the prompt in the MATLAB Command Window) and MATLAB is interpreting that line of code as an attempt to index into that variable instead an attempt to call the function.
Rename or remove that variable.

Thanks I realized it wasn't giving an error when I used clear all in the beginning and just changed the variable name from "input" to "fileInput"
