I assigned a 6x6 matrix (with 36 squares) a number. Suppose to run the function and choose up to 5 squares (#1-36) And after choose a percentage (0.0, 0.2, 0.4, etc up to 1) And those squares suppose to change those colors based on the percentage. And it is suppose to do that for each parameters (potholes, cracks, etc). And if any of the squares are chosen more than once, than RGB suppose to activate and that specific square suppose to change to that specific color. Cracks are specifically blue, Potholes are red and delimination is green. I am stuck on how to make these conditions work. Please Help. Any help is greatly appreciated. Thank you

Sorry about the mix up Sami, and thank you Saha.
This is how i designed my App designer. Location there is 36 locations since there is 36 squares inside the black box (Upload another imagine to show what i want as results)
I want to be able to put location (1-36) and be able to choose how much percent of that color i want. For example.. Location 1,5,8,10
percentage .2,.4,.6,.1
Than the box 1,5,8 and 10 will change to the color blue based onn RGB. .2,.4,.6 and .1 (different colors of blue)
Once you put information for all of the parameters.
This is how i want the results.
The code i used for this result was
n = 6; % number of squares along x and y, 36 in total
figure;
hold on;
axis equal;
% width of square divided by two, No spaces between squares
sqrWidthBy2 = 0.5;
% set the axis limits
axis([sqrWidthBy2 n+sqrWidthBy2 sqrWidthBy2 n+sqrWidthBy2]);
% array for the fill graphic object handles
sqHandles = zeros(n,n);
% array of colours (red, green, blue, black)
colours = ['r','g','b','k'];
% loops to create the squares
for x=1:n
for y=1:n
clr = colours(randi(4));
sqHandles(x,y) = fill([x-sqrWidthBy2 x+sqrWidthBy2 x+sqrWidthBy2 x-sqrWidthBy2 x-sqrWidthBy2],...
[y-sqrWidthBy2 y-sqrWidthBy2 y+sqrWidthBy2 y+sqrWidthBy2 y-sqrWidthBy2],clr);
end
end
But that code is not working since i need to assign a number to each square in order to have a location.
I am thinking of instead of this since it seems impossible, to instead just use a drop down menu where you choose only the percentage of cracks, potholes and delimination. And the squares changes color based on this code that i wrote for the 36 squares
rectangle('Position',[0, 0, 1, 1],'FaceColor',[1 0 0])
rectangle('Position',[1, 1, 1, 1],'FaceColor',[1 0 0])
rectangle('Position',[2, 2, 1, 1],'FaceColor',[0 1 0])
rectangle('Position',[3, 3, 1, 1],'FaceColor',[0 1 0])
rectangle('Position',[4, 4, 1, 1],'FaceColor',[0 0 1])
rectangle('Position',[5, 5, 1, 1],'FaceColor',[0 0 1])
rectangle('Position',[1, 0, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[2, 0, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[3, 0, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[4, 0, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[5, 0, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[0, 1, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[0, 2, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[0, 3, 1, 1],'FaceColor',[0 0 0])

rectangle('Position',[3, 1, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[4, 1, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[5, 1, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[3, 2, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[4, 2, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[5, 2, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[1, 3, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[2, 3, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[4, 3, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[5, 3, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[1, 4, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[2, 4, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[3, 4, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[5, 4, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[1, 5, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[2, 5, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[3, 5, 1, 1],'FaceColor',[0 0 0])
rectangle('Position',[4, 5, 1, 1],'FaceColor',[0 0 0])
This is the results that i want to happen
That one seems easier. Im just having a hard time connecting drop down menu to the function. I am not being able to get it to work when you choose the percentage for it to actually change the squares to that specific color. Im trying to use "If elseif else" statement but im struggleling.
I hope this clarifies it a lot better.

So I have tried with your first gui option.
I have created a matrix having vectors for rectangle positions. You can directly take input from your gui and use that index to select corresponing position from that matrix and color them (from correspoding percentage field). I assume you can do that.
Here I have implimented the same logic but colored the positions randomly (keeping your convention).
% this part you can keep in your startup function
a=zeros(36,4);
lm=1;
for yindx=1:6
for xindx=1:6
a(lm,:)=[xindx-1, yindx-1, 1, 1];
lm=lm+1;
end
end
% Here I have colored the positions randomply. You can take color percentage input and apply accordingly
colours = ['r','g','b','k'];
figure
for lm=1:36
clr = colours(randi(4))
rectangle('Position',a(lm,:), 'Facecolor', clr)
end
