please ,write a code to 3D plot this file .

column 1,2,3 are x,y,z respectively. please write the code . thanks

Answer 1

I am unsure about the specific type of 3D plot you require. I reviewed your previous questions and found that you have already learned how to extract the data. Once you have the coordinates, you need determine the type of 3D plot for them.

data= readmatrix('scd.xlsx');
x   = data(:,1);
y   = data(:,2);
z   = data(:,3);
scatter3(x, y, z)   % <-- probably this line is new to you

[Ali Moosazadeh]

can you write the code using surf function ?

Answer 2

[Torsten]

data= readmatrix('scd.xlsx');
x   = data(:,1);
y   = data(:,2);
z   = data(:,3);
F = scatteredInterpolant(x,y,z);
xq = linspace(min(x),max(x),100);
yq = linspace(min(y),max(y),100);
[Xq,Yq] = meshgrid(xq,yq);
Zq = F(Xq,Yq);
surf(Xq,Yq,Zq)
colorbar
