Try adding a variable doDisplay to toggle if the densities are displayed. Add this condition with an elseif block.
i do not understand what we are supposed to do in the above question(bold). this question is a part of futher practice in mathlab oramp. decision branching topic futher practice section in matworks course for basic matlab. how do i solve tha bove question

Shivaani - I think that all the code is asking you to do is to add another variable called doDisplay and an elseif that would check if this variable is true. If so, then you would plot the densities. So there would be two ways to plot the data - either through the doPlot or with the doDisplay
if doPlot
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
else
disp("The density of " + element ...
+ " is " + density)
end
You would need to declare and initialize the doDisplay variable too.

I'm not sure then...I added the above code and was able to proceed/pass. Are you sure that you have defined doDisplay?

This is what I did. I ran it numerous times. both doPlot and doDisplay have to be 0 in this scenario in order for the text to display instead of the plot.
doPlot = randi([0 1])
load datafile
density = data(:,1);
doDisplay = randi([0 1])
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
else
disp("The density of " + element ...
+ " is " + density)
end

Hi, I think the instructor might mean the following:
doDisplay = 1-doPlot
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
disp("The density of " + element ...
+ " is " + density)
end

Hi.
The instructor asks what hapenned when doPlot and doDisplay are both equal one or they both equal zero.
If we define doDisplay=1-doPlot, the cases above are not possible.

This is imo the best interpretation of the task at hand and a great solution.

My interpretation to this practice is to create another variable (doDisplay) with random number (0 or 1) just like the (doPlot), then use it as a second condtion for (elseif):
doPlot = randi([0 1])
doDisplay=randi([0 1])
load datafile
density = data(:,1);
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
disp("The density of " + element + " is " + density)
end
When:
doPlot = 0 and doDisplay = 0, then nothing displaied
doPlot = 1 and doDisplay = 0, then plot displaied
doPlot = 0 and doDisplay = 1, then density displaied
doPlot = 1 and doDisplay = 1, then only plot displaied
The point of this practice is to explain that second condtion will executing only when it met it's condtion and first condtion is not.

a Simple trick that i follow is,
at beginning I also not understand,
so we read it thrice by breaking sentance.
apply simple common logic.
we understand it.

This is the way I did it because I was under the impression that they are asking us to do recursion here, but I may be wrong.
doDisplay = randi([0 1])
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
doPlot = 1
else
disp("The density of " + element ...
+ " is " + density)
end

they are also asking what happens when they both equal zero, or when only doDisplay equals one?What's the ans for this

try this, i think it's the answer
doDisplay=randi([0 1])
if doPlot == 0
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
disp("The density of " + element ...
+ " is " + density)
end

doDisplay=randi([0,1])
doPlot=randi([0,1])
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
elseif doDisplay == 1
disp("The density of " + element+ " is " + density)
end
