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.

What have you already tried? Have you read the doc for the surf function?

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 !
