Matrix condition in while loop

Hi

I've been trying to use while loop with the matrix condition, but it doens't work.

I got an error message, "Index in position 1 exceeds array bounds."

Could you tell me what the problem is?

Thank you very much in advance.

for i = 1:10
    EP(1,:) = EP1;
    while (abs(EP(i+1,:)-EP(i,:)>0.1))
        for j = 1:4
            a(j) = EP(i,1) - s(j,1);
            b(j) = EP(i,2) - s(j,2);
            c(j) = EP(i,3) - s(j,3);
        end
        .
        .
        .
    end
end

I don't know if this solves your problem, but

while (abs(EP(i+1,:)-EP(i,:)>0.1))

should probably be

while abs(EP(i+1,:)-EP(i,:))>0.1
