Vector Operation in Matlab? -

can body me explain line 7 of code. line

temp(min(temp,[],2) >=1 & max(temp,[],2)<=n,:) 

do in code?

line 7 of code throwing me off

 n=10;  h=-1;  j=0;  i=1:n      j=1:n          temp=[i-1,j;i+1,j;i,j-1;i,j+1];          ngh{i,j}=temp(min(temp,[],2) >=1 & max(temp,[],2)<=n,:);      end  end 

that line selecting rows of temp have values between 1 , n, , assigning submatrix ngh{i,j}.

note that

• min(...,[],2) or max(...,[],2) gives minimum or maximum of each row;
• the logical comparison 1 or n , & operation result in logical index vector, used address desired rows of temp (and columns).
