Hello, I am currently working on my project and I am new to Matlab. My question is how to plot straight line vector with specific axis? For Example, I want to plot horizontal line that starts from 1450 to 1470 ( this is the x -axis )

plot([1450 1470],[0 0]) % this line will be at y = 0 because I've given plot [0 0] as the y-coordinates
xlim([1400 1500]) % set the x-limits of the axes to something beyond the horizontal line so you can see it

Hello Abdullah, you can use the plot function and give the x- vector as per your requirements like shown here :
x = [1450, 1470]; % x-axis limits
y = [5, 5]; % y-values for the horizontal line, you can set your value, 5 is used here for just as example
plot(x, y, 'k-') % 'k-' represents a black solid line
xlim([1450, 1470]) % set the x-axis limits
Also find a documentation of the 2-D graph plots here : Link

@Abdullah Alasfour I understand that you want to do bandpass filtering of a signal in the Fourier domain. While I don't have any examples of that exactly, I do have some other Fourier filtering demos that might help or at least be interesting. They are attached.
