Hello everybody,
I have a set of snr values for defects in a concrete specimen for different depths as attached in excel sheet. I used the wavelet method to analyze them into several levels.
Anyhow, I need them to be plotted into 3D by using the command surf. Would snybody help me with that?
Thank you in advance.

Try this :
snr_data = xlsread('snr values.xlsx');
depth = [1,2,3,5];
level = 1:7;
depth_mesh = meshgrid(depth,level).';
level_mesh = meshgrid(level,depth);
surf(depth_mesh,level_mesh,snr_data)
I hope it helps !
