All language subtitles for 05_getting-started-with-the-programming-assignments.en

Hello, this tutorial is designed to
introduce students to MATLAB Online and

its use in solving the programming
assignments for this course.

The goal of these assignments is to
help in visualizing the key concepts

taught in this course.

Let's get started.

The first thing that we observe
is a problem description,

where details regarding the assignment and
its requirements are mentioned.

This section often contains links to
download files for your desktop MATLAB.

We recommend using the desktop version
frequently when building your solutions,

as it helps to inspect your variables and
develop your code.

For function problems,
there are two code boxes.

The first code box is where you implement
the constants for the assignment and

it'll often contain some
code to get you started.

The second code box is for testing.

This box will consist of some
code to test your function, but

can be modified to test for
different scenarios.

The Run Function button runs the code
to call your function box and

displays any output there.

The Submit button tests your function and
returns the result.

Let's see how this works.

In this example, we are going to create
a location matrix above the z-axis for

a given angle in radians,

which is given by the equation
in the problem description.

So our task is to create a matrix
according to the formula shown.

Let's go ahead and plug in the formula.

Now that I think my function is done,

let's use the Run Function button to
test if my function works as expected.

Always test a function before
pressing Submit to make sure there

aren't any syntactical errors.

Great, our function runs and
we see the rotated vector.

Remember, we can modify this code to
test the function multiple times.

Let's go ahead and change the vector and
run this code again.

Now that we think our function's correct,
let's hit Submit.

Oops, looks like we made a mistake.

Notice the two levels of feedback.

The feedback in red directly
is from creating code.

The feedback in brown is a additional
set of hints provided regarding possible

errors.

So in this case,
I have the error because of negative sine.

Let me update the code and try again.

Great, now we have all green checks,

implying we have successfully
passed the problem.

Don't worry if you get stuck.

Code rarely works the first time and

the problems in this course
are quite challenging.

So pat yourselves on the back
when you get them right.

When you want to get help in the forum,s
include three things in your post.

The assessment descriptions that failed or
that you have questions on.

The red error message returned.

Now this can vary from the type of error,
description of error probed or

pseudocode outlined in your approach.

Please do not post any actual code in
the forums even if it is not working.

Thank you.
