MATLAB Onramp course error

I am running the MATLAB Onramp but it stalls at 11.1 The MATLAB Editor: (2/2) Practice, (71%)

The error is "There was an issue communicating to the MATLAB compute resource". Execution halts at the same place every time.

[Anushka Tilekar]

Is the MATLAB Onramp course available free of cost ? Will I get a certificate of completion after finishing it ?

[Walter Roberson]

Yes, and Yes.

[Ishaan Davariya]

I am facing the Same problem!!

[SIRAJ]

its does had any solution plz share it...

[Vishnu Sood]

delete all the previously typed code then copy and paste from sol. space

Answer 1

[Richard Chukwu]

Same with me. I'm on the fundamentals and I get this error at intervals. Even though my connection is okay.

[Laura Jones]

I think those features must be broken and no one is bothering to fix them because the course is free.

[SIRAJ]

frds one solution i got it first delete all initial lines see the solution then type it u definitely get crt answer try it...

Answer 2

[Mark Oliver]

I restarted my computer and never had the issue again.

[Sathish]

Ok

Answer 3

[KANISH THAKUR]

don't use "..." after "element", after finishing the term inside the bracket close it by using semi colon.

[mehdi benbraik]

yes great ; thank you friend , its ok new

if doPlot
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
else 
    disp("The density of " + element + " is " + density);
end

Answer 4

[KAMLESH SINGH]

x = rand
if x > 0.5
    y = 3
else
    y = 4
end

TASKModify the script so that when the if condition is not satisfied, the following line of code is executed:

disp("The density of " + element ...
    + " is " + density)

Hint

Submit

Hint

Modify the if statement to be an if-else statement.

In the else body, use the code as shown above.

Test Results:

Incorrect!----------------------------------------------Why the result is incorrect???? When the code written in Task 1&2 is correct

Are the densities displayed when doPlot is 0?

Are the densities not displayed when doPlot is 1?

Further Practice

Decision Branching

Instructions are in the task pane to the left. Complete and submit each task one at a time.

Do not edit. This code creates a random number to test the if statement.

doPlot = randi([0 1])

This code loads the data.

load datafile

density = data(:,1);

Task 1 & 2

if doPlot

plot(density)

title("Sample Densities")

xticklabels(element)

ylabel("Density (g/cm^3)")

else

disp("The density of" + element ....

+ "is" + density)

end

What is the solutions of decison branching 13.1

[rojin Arikan]

I have this problem too can you help me?

[mehdi benbraik]

i have the same problem, did you find a solution to this problem ?

[Pooja Roy]

I faced the same problem and my course remains incomplete because of that.

[Laura Jones]

I am unable to complete the course because it hangs in all of the project segments after the first few tasks.

[Thabiso Johannes Khune]

if doPlot
    plot(density)
    title("Sample Densities")
    xticklabels(element)
    ylabel("Density (g/cm^3)")
else 
    disp("The density of " + element + " is " + density);
end

[Walter Roberson]

@Thabiso Johannes Khune

If you are doing the same task as some other people have posted, then you are not supposed to do those lines unless doPlot is 1 . Your code is doing the lines if doPlot is non-zero. For example if doPlot were 2 then the task would require that the lines not be executed.

[GUDIPATI SRINIVASULU]

1. if doPlot ==1
2. plot (density)
3. title("sample Densities")
4. xlabel("Element")
5. ylabel("Density (g/cm^3.")
6. else
7. disp("The density of " + element +"is"+num2str(density) + " g/cm^3.");
8. end
