Hello to everyone. I extracted the histogram of the data I have. I wrote this code for it.
I want to calculate mean square error to see its compatibility. If I did it with histfit, I would write a code like this
However, I don't know how to calculate the mean square error because I fit manually. I would be very happy if you could help with this.

@Image Analyst signalhist_poz is my data. I would be very grateful if you could help me calculate the mean square error. I still haven't found a solution

I know that. But did you see my comment? Read it again. You still have not attached your data and I'm not about to recreate it manually from a bar chart. Please give it to us in a .mat file with the paperclip icon.

You have already computed in the last line of the code. Maybe you meant root mean square error. If so,
MSE = mean(fit_err.^2); % Mean square error
RMSE = sqrt(MSE); % Root mean square error

What I want to ask here is how to calculate mse without using the histfit command. I did not create the graph with red lines on the graph with the histfit command. I created this red chart with the first code I wrote. So I can't use histfit in mse code. If you want to take a look, I added my .mat file in the comments.
