Create Checkerboard using matlab

     I came across the matlab built in function checkerboard. And I tried to implement my own code.

First I declared the size of each square and then the number of rows and columns. Then I declared two matrixes initialized with zeros and ones. Using mod 2 I changed the colors or ones and zeros alternatively.

MATLAB CODE:

%Size of the square

sz=45;

%Number of rows

xvalue=8;

%Number of columns

yvalue=8;

%Intialize matrix A with zeros and matrix B with ones

A=zeros([sz sz]);

B=ones([sz sz]);

clear C

 m=sz;

 n=1;

 num=2;

for i=1:xvalue

    n1=1;

    m1=sz;

   

    for j=1:yvalue

        if(mod(num,2)==0)

        C(n:m,n1:m1)=A;

        num=num+1;

        else

        C(n:m,n1:m1)=B;

        num=num+1;

        end

       

        m1=m1+sz;

        n1=n1+sz;

    end

    if(mod(yvalue,2)==0)

    num=num+1;

    end

    n=n+sz;

    m=m+sz;

end
