i have to read an exel file which has iterations and cl/cd/cm and make a loop for plotting subplots for cl/cd/cm vs iteration which has different angle of attacks.

this is the code i am currently using.

dataset=readtable('output2''.xlsx');

dataset.Properties.VariableNames(1) = "iteration1";

dataset.Properties.VariableNames(2) = "cl";

dataset.Properties.VariableNames(3) = "iteration2";

dataset.Properties.VariableNames(4) = "cd";

dataset.Properties.VariableNames(5) = "iteration3";

dataset.Properties.VariableNames(6) = "cm";

y1=dataset.iteration1;

y2=dataset.cl;

y3=dataset.cd;

y4=dataset.cm;

subplot(3,1,1);

plot(y1,y2,'r--');

subplot(3,1,2);

plot(y1,y3,'b--');

subplot(3,1,3);

plot(y1,y4,'g--');

What is your question? Where are you having trouble?

Answer 1

[Star Strider]

If you need to do those plots in a loop, and assuming that the table variable names are (in order): iteration1, cl, iteration2, cd, iteration3, cm, set the loop up as:

figure

for k = 1:2:6

subplot(3,1,ceil(k/2))

plot(dataset{:,k}, dataset{:,k+1})

end

Add other plot enhaancements as necessary.
