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.

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

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

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

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

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
See Solution
Reset
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
WORKSPACE
COMMAND WINDOW
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

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.
