How can I change this loop to a switch loop?

    width=input('Enter a positive number:  ');
    disp(' ');
while width<0
    width=input('Enter a positive number:  ');
    disp(' ');
end

 %dimension input
   dimension=input('Input an integer greater than 1: ');
   disp(' ');
while (dimension<=1)
   dimension=input('Input an integer greater than 1: ');
end
   reorint=0;
while reorint==0
   if isreal(dimension)&&mod(dimension,1)==0
      reorint=1;
   else
      dimension=input('Input an integer greater than 1: ');
      reorint=0;
   end
end

 %colors input
color1=input('Enter 1st color: red(r), yellow(y), green(g), black(k), blue(b), magenta(m), white(w), cyan(c): ','s');
   disp('  ');
color2=input('Enter different 2nd color: red(r), yellow(y), green(g), black(k), blue(b), magenta(m), white(w), cyan(c): ','s');
   disp('  ');

 N=4;  
 R=width; 
 Phase=pi/4;
 theta=zeros(1,N); 

 for b=1:N
    theta(b)=2*pi*(b-1)*(1/4); 
end

 x1=R*cos(theta+Phase)/sqrt(2); %cosine function
 y1=R*sin(theta+Phase)/sqrt(2); %sine function

 for m= 0 : dimension-1 
    for n= 0 : dimension-1
        if mod(m+n,2) == 0 %adding your columns and rows to fill them with 2 different colors
            fill(x1+m*width, y1+n*width,color1);
        else
            fill(x1+m*width, y1+n*width,color2);
        end
        hold on;
    end
    hold on;
end

How can I change the for loops starting from where it say "for b=1:N;" and the rest of the code and make it into a switch loop? Even if I can't change all of it can a change a few parts of it?

' switch ' and loop statements are different and not directly interchangeable the way you sound to want them.

Why do you want to change those loops to a switch statement?

I just wanted to see it from a different approach and I thought that a switch statement could be done, but yes I understand that they're not the same thing, thank you!
