Question

MATLAB Practice Problem: Write a program which calculate the total profit/year by the end of each month in a year, given the variable P which stores profit/month for that year: P = [4 4 5 6 7 6 7 5 7 8 8 6]x1000

a) Set a loop up to calculate Ptotal(ii)=Ptotal(i-1)+P(i), to help decide about start/end conditions, use an iteration table.

b) Set up a loop to calculate Ptotal(i+1)=Ptotal(i)+P(i+1).

Answer 1

Here is the logic for you. Ofcourse, both loops will achieve the same thing. If you have any further queries, just get back to me.

P = [4 4 5 6 7 6 7 5 7 8 8 6]*1000;

display (P); %Displays the monthly profit.

Ptotal = [0 0 0 0 0 0 0 0 0 0 0 0];

%a) Set a loop up to calculate Ptotal(ii)=Ptotal(i-1)+P(i), to help decide about start/end conditions, use an iteration table.

Ptotal(1) = P(1);

for i = 2:12

Ptotal(i)=Ptotal(i-1)+P(i);

end

display (Ptotal);

%b) Set up a loop to calculate Ptotal(i+1)=Ptotal(i)+P(i+1).

for i = 1:11

Ptotal(i+1) = Ptotal(i)+P(i+1);

end

Ptotal(12) = Ptotal(11)+P(12);

display(Ptotal);
