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!

Hi @Valeria Gallo
You can find some examples in the following links:
Response Surface Designs
Central composite design (CCD)
Box-Behnken design (BBD)
Example 1: A 2-factor central composite design.
dCC = ccdesign(2, 'type', 'circumscribed')
dCC = 16×2
-1.0000 -1.0000 -1.0000 1.0000 1.0000 -1.0000 1.0000 1.0000 -1.4142 0 1.4142 0 0 -1.4142 0 1.4142 0 0 0 0
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)
dBB = 15×3
-1 -1 0 -1 1 0 1 -1 0 1 1 0 -1 0 -1 -1 0 1 1 0 -1 1 0 1 0 -1 -1 0 -1 1
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

Hi Sam Chak, thank you for your answer. I have already seen the pages, but I need to find the way to run the subsequent steps: coding and uncoding the variables, find the significant factors, find the optimal conditions, find the predicted value of the response under optimal conditions and so on

Dear Valeria Gallo
Do you find the answer?
actually I have the same problem and want to dimensionally optimize a heat exchanger as a final part of my matlab code using DOE.
