MATLAB: Rewrite function for loop in while

for loop

Hi all! How can I rewrite this for loop in a while?
for i = 2:sum(1: (rows - 1))
    if (i > sum(1: (x)))
        x ++;
    endif
    if ( (i == sum(1:(x))) || (i == sum(1: (x - 1)) + 1))
        A(i,i) = 5;
    else
        A(i,i) = 6;
    endif
endfor

Best Answer

i=2;
while i <= sum(1:rows-1)
    if i > sum(1:x)
        x=x+1;
    end
    if (i == sum(1:x)) || (i == sum(1:x-1)+1)
        A(i,i) = 5;
    else
        A(i,i) = 6;
    end
    i=i+1;
end
