Need some help with loop
显示 更早的评论
Hi, I need some help with creating a loop so every number of v is evaluated with every p in the LoF formula. Meaning 50*5^2*FVF/FV for the first v-value and 50*10^2*FVF/FV for the second v-value, and when it is done with p= 50, starting over with p=100 and evaluating all the v-values with respect to that p and so one.
I appricate the help.

Are you required to use a loop for this homework problem? There is a better way to do it that does not require a loop, but if you're required to use a loop we can do it that way.

First thing, rather than posting pics of your code it would be better if you copy pasted the actual code.
what you are looking for is a nested for loop. Here is the code:
v = [5:5:40];
p = [50:50:300];
FVF = 0.001;
Fv = 27056;
LOF = zeros(length(p), length(v));
for i = 1:length(p)
for j = 1:length(v)
LOF(i, j) = p(i) * v(j)^2 *FVF/Fv;
end
end
I stored the values in LOF in form of a matrix, where each row coreesponds to the values obtained by the corresponding entry in p.

No loop needed.
[v,p]=meshgrid(5:5:40,50:50:300);
FVF=.001;
Fv=27056;
LoF=p.*(v.^2)*FVF*Fv;

EDIT: Division by Fv needed in LoF equation

@David Hill The point of homework isn't to get the answer...The point is to learn. So if you're going to give someone the answers to their homework, at least put in some effort to teach them why you're doing each step.
