Hi, I am really new to MatLab so apologies if this is an exceedingly stupid question or the answer is glaringly obvious...
I have a large amount of data in the following structure:
A rho RMSE
500 0.10 NaN
500 0.11 NaN
500 0.12 12.34
...
500 0.50 56.78
600 0.10 9.01
...
3000 0.50 NaN
I need to plot the surface to see how the RMSE value changes with the value of A and rho. I then need to interpolate the surface order to obtain all the A,rho pairs that give an RMSE value of zero (i.e.interpolate along the zero contour).
I understand that surface plotting requires the data to form a grid: I therefore follow this to restructure my data (as it is in the same format) and can thus use surf() to plot the surface. My question is thus: How do I display the Z(RMSE) = 0 contour on top of the plotted surface?
How do I 'interpolate' the surface such that I produce a list of x,y combinations that give z=0?
Any pointers in the right direction would be gratefully received.
Many thanks
