plot mean square error

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))
