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

When I format your question for you, it seems you're missing an end statement. Is this intentional?
Also, what exactly is your question? What exactly do you want to happen?
As Rik mentioned above one "end" statement is missing. Moreover, the second "else" does nothing and thus, it should be removed.
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
end
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
end

for i = 1:100
if ~(sln2.Error<=1)
Ext.W22=beta*Ext.W22;
Ext.W22List(i) = Ext.W22;
end
sln3.Error=max(abs(Ext.P_gen_scaling-Ext.P_gen_scaling_3));
SLN3(i)=sln3;
if (sln3.Error<=0.1)&&(sln2.Error<=1)
break;
end
end

Thanks alot this worked . But later on if I have more than 2 statments then I need to add 2nd &&?

%% 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) && (sln2.Error <= 1)
break
end
end
