I had correct code within the
The only thing I changed was uncommenting the different scenario lines as required to evaluate different measurements, as shown in the video. In the end, I think I put a comment back with different content within the comment. Should this matter?
When I submitted it (missing leading white space):
The observed results were identical to those shown by Sebastian during the explanatory video.
Could the homework evaluator please be changed to pull my block out, and run it within the pristine question context?
Here's my code block:
Measurement uncertainty isn't by definition equal to dt, though in this case it happened to be. If the grading program varied dt to test your matrix under multiple conditions, your uncertainty figures would be off. That might explain your issue.

Hello, I submitted the following as my answer to homework 2.6 and it was graded as incorrect:
P = matrix([[0, 0, 0, 0],
F = matrix([[1, 0, dt, 0],
H = matrix([[1, 0, 0, 0],
R = matrix([[0.1, 0],
I = matrix([[1, 0, 0, 0],
All the results were EXACTLY equal to what was shown in the explanation video.
Is there a bug in the auto-grader? Because I'm sure that my results are correct!
And also, wouldn't there be a possibility to make the auto-grader a little more flexible? It seems that your whole homework is graded wrong, if you insert just a single character in a place where you're not supposed to.
In my opinion it matters that the code+results are correct. And not that you have every single space exactly like in the solution!!!

Did you make your code in an external interpreter such as IDLE, before copying it in the Udacity editor?
If so, maybe you are suffering from the EOL bug I described here:
