assignment #6 Q2

Q(2):Create a 256 x 256 matix with ones in the (i,i+1) position and zeros elsewhere.

Ans.

A=zeros(256);

for x=1:256;

A(x,x+1)=1;

end;

imshow(A)
--------------------------

A 256 x 256 matrix with 1's in the (i,i+1) position and zeros elsewhere can be coded as follows:

A=tril(ones(256),1);

B=tril(ones(256),0);

A-B

----------------------

In one line:

A=(tril(ones(256,1))-tril(ones(256),0)

imshaow(A)
