plot mean square error
显示 更早的评论
hi,
i want to plot mean square error in matlab
i use the code: MSE=mean((YP-Yd).^2);
it gives me only one value, i want to know a code that gives me a vector to plot it
thanks in advance

Can you explain? You have two vectors YP and Yd, the mean of YP-Yd is one number, why are you expecting the result to be a vector?

you have to use for loop for iteration through your data length or if you are using filter then put filter length as a value for iteration like
N = length(input);
for i = 1:N-1
mse(i) = mean((y(i)-x(i)).^2)
end
plot(abs(mse))

@dawit mamo hi. Could you please take a look at my question in this link? I really can't find the answer. I fit the distribution manually. But now I can't calculate the mean square error of the histogram with manual fit. https://uk.mathworks.com/matlabcentral/answers/868318-how-to-calculate-mean-square-error-in-histogram?s_tid=srchtitle

t= length(simulation_time);
for i = 1:t
mse(i) = mean((y(i)-x(i)).^2)
end
plot(abs(mse))
%% or
for i = 1:t
mse(i) = mse(i)+ mean((y(i)-x(i)).^2)
end
plot(abs(mse))
