Hi there,
I have 6 sets of x and y data, each set of data representing a specific frequency (20 kHz, 50 kHz, 100 kHz, 200 kHz, 1000 kHz).
I can use plot3 to plot these curves in matlab:
x_y_z_data.PNG
How can I interpolate between these curves to be able to estimate x and y values for any frequency between 20 and 1000 kHz?
Thanks in advance!
