I am trying to get grey colored plot points on my 3D scatter plot, I am unfamiliar with scatter3. From the error messages I am getting using the conventional method (on a regular plot, shown below) - I am assuming there should be an established color vector.

This is what I have currently

scatter3(X,Y,Z,'filled', c, [17 17 17]);

在 MATLAB Online 中打开

rgb triplets are normalized between 0:1

https://www.mathworks.com/help/matlab/ref/colorspec.html

To convert from decimal code, divide by 255.

[17,17,17]./255
% equals
[ 0.066667     0.066667     0.066667]

The color gray is

% RGP TRIPLE                           %CSS3 proposed standard name: https://www.w3.org/TR/css-color-3/
[0.5          0.5          0.5]        %gray
