Can anyone help me with run a complete CCD or BBD experimental design in matlab? Actually I use RStudio for run my DoE but i would like to learn how to perform these in Matlab.
I found this page https://it.mathworks.com/help/stats/design-of-experiments-1.html that give me some information but this is not enough...
I would like to know also the script for give the experimental responses, extimate coefficient, perform the ANOVA and response surface and so on..
Thank you so much!

You can find some examples in the following links:
Example 1: A 2-factor central composite design.
dCC = ccdesign(2, 'type', 'circumscribed')
plot(dCC(:, 1), dCC(:, 2), 'ro', 'MarkerFaceColor', 'b')
X = [1 -1 -1 -1; 1 1 1 -1];
Y = [-1 -1 1 -1; 1 -1 1 1];
line(X, Y, 'Color', 'b')
axis square equal
Example 2: A 3-factor Box-Behnken design.
dBB = bbdesign(3)
plot3(dBB(:, 1), dBB(:, 2), dBB(:, 3), 'ro', 'MarkerFaceColor', 'b')
X = [1 -1 -1 -1 1 -1 -1 -1 1 1 -1 -1; ...
1 1 1 -1 1 1 1 -1 1 1 -1 -1];
Y = [-1 -1 1 -1 -1 -1 1 -1 1 -1 1 -1; ...
1 -1 1 1 1 -1 1 1 1 -1 1 -1];
Z = [1 1 1 1 -1 -1 -1 -1 -1 -1 -1 -1; ...
1 1 1 1 -1 -1 -1 -1 1 1 1 1];
line(X, Y, Z, 'Color', 'b')
axis square equal
