Hi all,
I am trying to plot a vector in a graph with 3 axes, but I am confused how to do it. I tried with plot 3.
The matrix is
A=[20 15 120 0.85;20 9 100 1.35;30 6 100 0.18; 30 9 140 1.65; 40 6 80 0.25;40 12 100 1.42]
So I would like to plot the 4th column, with 3 axes that are defined by the other three columns.
any ideas how to do that?
thanks!

yeah actualy x,y,z are columns 1,2 and 3. And the 4th column is the f(x,y,z).

How would you like the data point to look for different values of the 4th column? Let's say one (x,y,z) point had a value of 10 and another had a value of 140. In what way would they look different?

In this universe, we are limited to 3 large dimensions (although 11 may actually exist). The dimension in the plot can be the color of the markers:
figure
scatter3(A(:,1), A(:,2), A(:,3), 75, A(:,4), 'p', 'filled')
grid on
