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

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....
