Estrarre l'intervallo di dati impostando il valore sulla matrice

Hi, i have a question: i would like to extract data range from matrix composed by 3 column (one of them is the Z axis) , the data beloging to a thickness range of 20 cm, along the path.

Thank you so much

Please provide more details. Show the data

• Use griddata to interpolate the data
• Use slice to create slices

thank you so much your answer. I used slice command and it works, but i want create a script that it should be able to slice automatically the crow tree point cloud along z path.

Do you have any tip for me?

Sorry, misunderstood you a bit. Use contour

xx = linspace(min(x),max(x),20);
yy = linspace(min(y),max(y),20);
zz = linspace(min(z),max(z),20);
[x1,y1] = meshgrid(xx,yy);          % create a mesh
z1 = griddata(x,y,z,x1,y1);         % interpolate the data
contour(x1,y1,z1,zz)

I don' an opportunity to look in your data. Can you make a printscreen or something?

Hi, i have attached the .txt data. It shows a olive tree point cloud. I want slice one from bottom to the top setting a value ( such as 0,10 m ) along Z column. and export each singular slice with a growing name ( Slice1, Slice 2. Slice3 and go on).

How can i solve this question?

Thank you.

Please don't produce answers, use comments section. I don't have MATLAB on my computer, i can't plot the data. Do you know how it should looks like? Please show some pictures so i could help you

Thank you for your tips. I solved my question.
