3D surface plot from 3 columns of excel data?

Total newbie here.

I have 3 columns of data and I want to create a 3D scatter plot. I was able to impot the columns as three 18 x 1 cell arrays in m y workspace. Can anyone help with some basic steps? Thanks!

The first basic step is the enter doc scatter3 in the MATLAB command window. In the documentation presented, you'll find several examples that should help you get started. Good luck.

thank you Scott. unfortunately, that is where I went first and could not find anything to help me.

Attach your data. It depends on whether data is stuctured or unstructured.

[Scott MacKenzie]

Well, in that case, it might help if you posted your data and any code you've written so far.

[John Schneider]

thanks again. this is what I imported

I tried the following commands:

plot (a,b,c)

surface (a,b,c)

I know this must be trivial, but this is my first time using Matlab

Here you go...

T = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/645855/P3%20data.xlsx');
x = T{:,2}; % Speed
y = T{:,3}; % Range
z = T{:,4}; % Cost
scatter3(x,y,z);
xlabel('Speed');
ylabel('Range');
zlabel('Cost');

that is awesome Scott, thanks!
