Stuck at MATLAB Onramp

Hey guys.

I'm stuck on the self-paced MATLAB Onramp course. The section is 13.2 Decision Branching and I'm at Furher Practice. I have no idea how I'm supposed to add the "elseif" statement with "doDisplay". Can anyone show me thier take on this problem?

[Sneham Shrikant Vaidya]

if doPlot

plot(density)

title("Sample Densities")

xticklabels(element)

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

else

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

end

//just paste this code

or remove the dashed line in front of element is soluttion

Hi,

The question is a bit ambiguos at start but if you look at the code carefully you will understand the each step.

It asks you to create a "doDisplay" variable, you can do that by creating a variable same as doPlot below the doPlot variable.

doPlot = randi([0 1]);
doDisplay = randi([0 1]);

It asks you to add an elseif block which can toggle whether it can display the densities or not.

if doPlot
    ...
elseif doDisplay
    %Print the densities
else
    %Print nothing just leave it with a comment for readability.
end

[Walter Roberson]

Yes, it is available free. My understanding is that there is a certificate upon completion.

[Lixin Zhen]

Will there be a certificate upon completion of the MATLAB self-paced fundamentals course (16.5 hours)?

Load the file Cchord.mat.

Create a variable named n that contains the number of elements in y. Then use n to create an evenly-spaced vector t that starts at 0, ends at n-1, and has elements that are spaced by 1.
