How are multiple for loops handled by matlab?

Hello, How's Matlab dealing with the following code? Is matlab checking the if condition like this: if 1=10 and then if 2=10 or if 2=50? My aim is that after the condition is true, every C(k) is added a C(n) till C(k)==C(n+1).

    for k = 1:100
       for n=[10,50,70]
           if C(k)==C(n)
           C(k:n+1)=C(k:n+1)+C(n)
           end
       end
end

What is c(k) here?

    assign k=1
       n=10
         if c(1)=c(10) 
            if yes then only c(1 to 11)=c(1 to 11)+c(10)
             otherwise skip if condition
          end 

    k=1, now n=50
         if c(1)=c(50) 
            if yes then only c(1 to 51)=c(1 to 51)+c(50)
             otherwise skip if condition
         end 
       k=1n n=50

do the same
finished inner loop next 
k=2 and rest are same n=10, n=50, ...

Welcome!

Please note: for one k value inner loops for n=10, 50 and 70 completed then only k=2 and do the same

This depends on how you nest your loops:

for k=1:100
 for n=[10,50,70] %this is the inner loop it will be executed 100 times
end
end

for n=[10,50,70]
for k=1:100 %this is the inner loop it will be executed 3 times
end
end

Your example will check for

C(1)==C(10)
C(1)==C(50)
C(1)==C(70)
C(2)==C(10) 
%...and so on

Do you think the execution after the if function is correct? Because nothing happens, not even an error....
