if and for loop

How to write a program for the following statements:

Cpv=0 if vi is less than equal to 10

          15 
Cpv=(1/15)∑(Vi^2-100)  if vi is more than 10
          i=1

Cpp=0 if Pj is greater than or equal to 18

    50
Cpp=∑(18-Pj)   if Pj is less than 18
    j=1

kindly help me out. Thanks in advance

Hey @adarsh, you can implement it with couple of if conditions and sum function, below i have attahced the code implementing the same:

% Example input vectors
Vi = [5, 12, 9, 15, 11, 8, 14, 13, 10, 7, 16, 6, 18, 4, 20]; % Length 15
Pj = [20, 17, 19, 15, 16, 18, 14, 13, 22, 21, 17, 19, 16, 18, 20, 15, 14, 17, 16, 18]; % Length 50

% Calculate Cpv
if all(Vi <= 10)
    Cpv = 0;
else
    Cpv = (1/15) * sum(Vi(Vi > 10).^2 - 100);
end

% Calculate Cpp
if all(Pj >= 18)
    Cpp = 0;
else
    Cpp = sum(18 - Pj(Pj < 18));
end

% Display the results
fprintf('Cpv: %.2f\n', Cpv);

Cpv: 69.00

fprintf('Cpp: %.2f\n', Cpp);

Cpp: 28.00

Hope it helps.

You don't need the if conditions because sum([]) is 0.

If the sum() were 0 then one of Cpv or Cpp would ahve come out as 0, but neither one does.
