In the below code if any of the error goes below the limit the loop break. But I want to break the loop if all of the conditions errors are below the defined limits. How can I modify this piece of code.

for i = 1:100
    if(sln2.Error<=1)
        break
    else
        % Update weights
        Ext.W22=beta*Ext.W22;
        Ext.W22List(i) = Ext.W22;
    end
    %% Convergance Check sub 2
    sln3.Error=max(abs(Ext.P_gen_scaling-Ext.P_gen_scaling_3));
    SLN3(i)=sln3;
    if(sln3.Error<=0.1)
        break
    else
    end

Yeah end is there . so there is no error with that . My question is that you can see that there are 2 break statments within the for loop. my for loop keeps on repiting when both of the if conditions are false but as only the single condition satisfies then the for loop breaks. But i want that even single condition is false the for loop shoulkd keep on repeteting.

Please consider this below code

for i=1:100

if(sln2.Error<=1)

break

else

% Update weights

Ext.W22=beta*Ext.W22;

Ext.W22List(i) = Ext.W22;

end

%% Convergance Check sub 2

sln3.Error=max(abs(Ext.P_gen_scaling-Ext.P_gen_scaling_3));

SLN3(i)=sln3;

if(sln3.Error<=0.1)

break

else

% Update weights

Ext.W23=beta*Ext.W23;

Ext.W23List(i) = Ext.W23

end
