I have to create a scatter plot from a copulapdf command and adding contourlines for the level [0.1:0.1:0.9]. I wrote this script to make a contour but i'm not able to specify the level. Which part of this script i have to modify and how?

rho = 0.5;
 n= 1000;
 s3 = copularnd('Frank',rho,n);
 figure
 scatterhist(s3(:,1),s3(:,2))
 hold on 
 [n,c] = hist3([s3(:,1),s3(:,2)]);
contour(c{1},c{2},n)

The argument, which can be found in the doc , is called 'levellist'

contour(c{1},c{2},'levellist',[1 5 10])

sets the levels to z=[1 5 10]

thank you for the reply! This is the code corrected with your suggestion:

rho = 0.5;
 n= 1000;
 s3 = copularnd('Frank',rho,n);
 figure
 scatterhist(s3(:,1),s3(:,2))
 hold on 
 [n,c] = hist3([s3(:,1),s3(:,2)]);
contour(c{1},c{2},'levellist',[0.1 0.1 0.9])
