How do I interpolate 3 variables to create a scatter plot?
显示 更早的评论
Hello everyone! I have 3 variables: frequency, amplitude and reflection coefficient in form of 41x10 arrays.
Now I would need to interpolate those reflection coefficients in smaller gaps of frequencies and amplitudes (i.e. 10 Hz instead of 20 Hz) in order to increase the resolution of my scatter plot.
Can someone help me?
Many thanks. Carlo
