i try do delete rows and columns that are zeros but it cut also part of shape .I use this code
u=I;
old=[];
new=all(~u);
while ~isequal(old,new)
u(new,:)=0;
old=new;
new=all(~u);
end
u(new,:)=[];
u(:,new)=[];
av=u;
av(~any(u,2),:)=[];
%radious of puple
figure, imshow(av,[]);

u = I;
zc = ~any(u);
u(:,zc) = [];
zr = ~any(u,2);
u(zr,:) = [];

data( all( ~any( data), 2 ), : ) = []; % removes all rows with all zero
data( :, all( ~any( data ), 1 ) ) = []; % and columns
