I am using the code shown below to plot the FFT of some data. My issue is that the "resolution" seems poor, as the x axis is in increments of 0.2. I would like much finer plotting of points, and have recently seen the Zero Padding method. However, everytime I try to implement other solutions on MATLAB answers, I cannot seem to increase the resolution. Could anyone help me with the necessary code for my specific case?
P1(2:end-1) = 2*P1(2:end-1);
