Hello,
I'm new to matlab. So forgive me if this is a stupid question. I'm analyzing some MATLAB code, and there is a line which plots the 1000th row of a matrix. However I don't understand where the y-values come from. Where do the y-valus come from?
Here is a link to the csv file of INT_I:
The code is:
figure('Name','INT 1000','NumberTitle','off'); hold on;
set(gca,'FontSize',30)
plot(INT_I(1000,:))
legend('1','2','3')
What I get is this:

"Where do the y-valus come from"
Your data.
Where do the X values come from? Read the plot help to find out.

INT_I(1000,:)
That is your y-values
plot(INT_I(1000,:))
Is equivalent to
plot(1:length(INT_I(1000,:)), INT_I(1000,:))
Due tell if it is not clear
