Hello, I'm new to matlab. For a homework I need to plot a spline from two vectors.
file = fopen('data_xi.txt');reel = fscanf(file, '%f', );fclose(file)file = fopen('data_yi.txt');imag = fscanf(file, '%f', );fclose(file)xx = 0:.05:8;yy = spline(reel,imag,xx);figure(1)plot(real,imag,'o',xx,yy);xlabel('Voltage(mV)') ;ylabel('Current(A)') ;
I'm not sure I understand how spline works, I just copied an example and tried to apply it to my case. When I run the code, the plot window opens but nothing shows up.
Thanks for any help
