I'm getting the error "Error using plot Vectors must be the same length", however I can't quite figure out where the error is in using plot. I am attaching a photo of the code.

Error using plot Vectors must be the same length

hello

a photo of a code is not very helpful

better if you can share the code itself and data to test it

have you at least checked the size of the data you are plotting ?

To add to Mathieu's comment, you are trying to plot n_for points in x vs (1 + n_for) points in y, which is not possible and thus you get the error.

Attached is a code snippet and data for it, I still can't find the error. In x or y should I change the length of the vector?

"In x or y should I change the length of the vector?"

Depends on what you want to do. What are you trying to plot? What is the expected output?

Michal Kalowski 2023-5-4

Projected and actual values are to be plotted in one plot for 44 data points

Is there any reason why you are concatenating x(end) with the data form yfor?

If it is important than you will have to adjust yfor, otherwise you can remove x(end) and plot against the data from yfor.

I don't quite understand the answer, can you point me to the piece of code that I should change and what to change in it?

Either try this -

plot(length(x)+(1:n_for), cell2mat(yfor), 'r')

or

plot(length(x)+(1:n_for), [x(end); cell2mat(yfor(1:end-1))], 'r')

Ok super. Thank you for your help

I have one more question, how to implement seasonal back differencing and first order back differencing into the sent code. I am attaching an example of such code that I would like to enter into my code.

dd = length(y_1d); kk = length(y);
for i =1:n_for
y_1d(dd+i) = yfor(i) + y_1d(dd-m+i); %seasonal back differencing
end 
for i = 1:n_for
y(kk+i) = y(kk-1+i) + y_1d(dd+i); %first order back differencing
end
