Plot 10 times and take the average
显示 更早的评论
Hello,
users = [10 20 30 40 50];
rates = [];
for i = 1 : length(users)
rates = [rates Function(users(i))];
end
figure(3)
plot(users,rates)
I have this code that calls another function 'Function' This function calculates the rates that i want to plot, but what i want to do is that for 10 users i want to plot the rates for 10 times and take the average and plot, the same goes with the 20, 30, 40 and 50 users. I want to plot every element in the array 'users' versus 'rates' which is calculated in another function 10 times and take the average of every 10 times and put the result of the 5 elements in a plot. Can anyone help?
Thank you :)

users = [10 20 30 40 50];
N = numel(users) ;
rates = zeros(1,N) ; % pre_allocation
for i = 1 : N
tempV = MyFunction(users(i)) ; % assuming V is vector of 10 elements?
rates(i) = mean(tempV)
end
plot(users,rates,'bo')

Does MyFunction(x) return a single number or a vector of 10 numbers?

You can create an inner loop:
for i = ...
tempV = zeros(1,10) ;
for k = 1:10
tempV(k) = MyFunction(users(i))
end
rates(i) = mean(tempV)
end
