Error using input function

I am receiving an error with MATLAB and I have absolutely no idea why.

MATLAB Version is R2018a.

This will show you why:

which input -all

I've found a script called input.m, but what am I supposed to do with it? I don't quite understand.

[Jayesh Kamboj]

K never mind I fixed it. Turns out I DID have a function called input already.

It's so easy to accidentally create a script file or variable with an existing MATLAB function name. The worse I have ever seen was a student create a created a script file called "edit". Geez that took a LONG time to figure out! lol.

You have a custom made function named input() which shadows the inbuilt function. Rename it or remove it from the path.

I don't have any function named input. I had one called 'input_lab2_ex3' but I changed that to 'inpu_lab2_ex3'. I am still receiving the same error.

What does Stephen comment output? Paste the output , so we can analyse.

[Jayesh Kamboj]

I clicked on the program, and this is what I found:

%INPUT  Prompt for user input. 
%   RESULT = INPUT(PROMPT) displays the PROMPT string on the screen, waits
%   for input from the keyboard, evaluates any expressions in the input,
%   and returns the value in RESULT. To evaluate expressions, INPUT accesses
%   variables in the current workspace. If you press the return key without
%   entering anything, INPUT returns an empty matrix.
%
%   STR = INPUT(PROMPT,'s') returns the entered text as a MATLAB string,
%   without evaluating expressions.
%
%   To create a prompt that spans several lines, use '\n' to indicate each
%   new line. To include a backslash ('\') in the prompt, use '\\'.
%
%   Example:
%
%      reply = input('Do you want more? Y/N [Y]:','s');
%      if isempty(reply)
%         reply = 'Y';
%      end
%

That’s NOT the OUTPUT of STEPHEN’S COMMENT.

[Jayesh Kamboj]

K never mind I fixed it. Turns out I DID have a function called input already.

[Jayesh Kamboj]

and output was 'built-in (C:\Program Files\MATLAB\R2018a\toolbox\matlab\lang\input)'
