4D Plot using Columns of Matrix

Question

回答： Divya Gaddipati 2019-8-13

I have a 340x5 matrix and I want to plot the 4th and 5th columns as the function of the first 3. Doing a point plot like the stem3 function.

X = A(:,1);   %Assume A is the matrix I imported from a file with the size above
Y = A(:,2);
Z = A(:,3);
F = A(:,4);
G = A(:,5);
figure
stem3(X,Y,Z)

But like this que 4th and 5th column are not in the plot. And I wanna do something like F = f(X,Y,Z) and G = g(X,Y,Z). For each row of the A matrix.

F = f(X,Y,Z) and G = g(X,Y,Z)

I don't understand. What does it mean?

figure, scatter3(X, Y, Z, 50, F, 'filled');

The scatter3 function can be used, where each point in F is plotted with a different color represented by F and 50 is the marker size.
