I wanna stop iteration when two matrixes difference approach zero.

for example,

A=[a;b;c;d;e;f;g;h]  %double 7x1
B=[m;n;v;x;z;p;j]    %double 7x1

I open while loop for equation and I wanna stop when A-B is equal approximately zero, but it never be zero.

if I write

while A-B~=0   
do "........."

infinite loop occuring.

tol=0.001
while sum(abs(A-B))>tol
   % do
end
