how to use output as input in same code

h = 2
for I = 1:15
E = 0
for el = 1:20
M = 1 +h
E = E + M
end 
end

how can I use the new value of E for each iteration?

The new value of E is used for each iteration of el .

Your E=0 resets E for each iteration of I

Dear sir, can you please cod for d same by rearranging

[Walter Roberson]

h = 2
E = 0
for I = 1:15
for el = 1:20
M = 1 +h
E = E + M
end 
end

I guess. Your question is not clear to me.

h=2
E=0
for ...
for ...
....
E=E+M  % Update E
end 
end

Role of I loop ??
