How to do iteration using while loop?

step 1

clc;
gb=3;gs=8;s=gb;b=gs; 
Eg=[50 100 150 175 200 250 300]; 
Egm=mean(Eg);
P=[20 15 10 5 1 0.5 0.1];  
Ns = [];    Nb = [];      Nsb = [];     
for n=1:length(Eg)     
    if Eg(n)>Egm
      Ns = [Ns n];
    elseif Eg(n)<Egm
         Nb = [Nb n];
    else
         Nsb = [Nsb n];
   end
end

step 2

X=(P(Ns)/s)-1 ;    
X=(P(Nb)/b)-1 ;    
X=Eg(Nsb) ;       
for i=1:1:Ns            
for j=1:1:Nb            
Es(i)=Eg(:,i)-X(i) ;
EsL(i)=sum(Es(i));
Eb(j)=X(j)-Eg(:,j) ; 
Eby(j)=sum(Eb(j));
p1=(sum(Eg(i))+Ns); 
p2=(sum(Eg(j))+Nb);
if EsL(i)>Eby(j)  
1s*(i)=sqrt((gb*P(i))/(p1(i))) 
1b*(j)=sqrt((gb*P(j))/(p2(j))) 
end
 elseif EsL(i)<Eby(j)
 2s*(i)=sqrt((gs*P(i))/(p1(i)))  
 2b*(j)=sqrt((gs*P(j))/(p2(j)))  
 else
end
end
end

I have to apply a condition

if s*(k+1)-s*(k)<=0.01,b*(k+1)-b*(k)<=0.01,X(k+1)-X(k)<=0.01

then terminate

else send this updated values to all n and go to step 2

where k is the no of iterations.

How to apply this iterative process using while loop?

Answer 1

[Walter Roberson]

k = 1;
while true
    do the stuff for step 2
    if s*(k+1)-s*(k)<=0.01 && b*(k+1)-b*(k)<=0.01 && X(k+1)-X(k)<=0.01; break; end
    send this updated values to all n whatever that means
    k = k + 1;
end

Ok,Thank you.But,I am applying this it shows an error ' Unrecognized function or variable 'do'.

Why is like this?

At the place where my code outline says

do the stuff for step 2

you should insert your code that implements step 2.
