I want to restart the loop from starting when a specific condition is met.

a = table2array(BRTSTestData);

c = 20;
f = 1;
s = 0;
for i = 1:5
    for j = 1:6
        s = s + a(i,j);
    end
    if s > 20
        f = f+1;
        a = a/f;
        break
    end
     for k = 1:5
         s = s - a(k,i);
     end
     

Now here I want to restart the first for loop from i = 1 when s > 20 and operate f = f+1. If I use break statement it terminates the loop and starts from next condition.

Sanyam - perhaps use a while loop instead.

a = table2array(BRTSTestData);
c = 20;
f = 1;
s = 0;
i = 1;
while i <= 5
    for j = 1:6
        s = s + a(i,j);
    end
    if s > 20
        f = f+1;
        a = a/f;
        i = 1;   % <--- reset i to one
        break;
    end
    for k = 1:5
        s = s - a(k,i);
    end
    i = i + 1;   % <--- increment i
end

while using break statement it gives control to the statement that follows the end of the loop. But I want to restart the following loop once again. please guide.

a = table2array(BRTSTestData);
c = 20;
f = 1;
s = 0;
i = 1;
j = 1;
while i <=5
    while j <= 5
        s = s + a(i,j);
        if s > 20
            a = a*f;
            f = f+1;
            a = a/f;
            j = 1;
            break  
        end
        j = j+1;
    end
    
    for k = 1:5
        s = s - a(k,i);
    end
    i = i + 1;  
end

I think in the code that I posted, the break should have been a continue

a = table2array(BRTSTestData);
c = 20;
f = 1;
s = 0;
i = 1;
while i <= 5
    for j = 1:6
        s = s + a(i,j);
    end
    if s > 20
        f = f+1;
        a = a/f;
        i = 1;      % <--- reset i to one
        continue;   % <--- end the current iteration and continue with the next
    end
    for k = 1:5
        s = s - a(k,i);
    end
    i = i + 1;   % <--- increment i
end 

Perhaps that is all that you need to do too in the new code that you have posted - change the break to continue.
