I have 5 vectors of related elements, in the sense that the first element of vector A is connected to the first elements of vectors B, C, D, E, the second with the seconds, and so on: they represents the x, y, z, phi and delta coordinates of points.
I'm searching for a way to plot this vectors as surface plot or scatterplot, but I really don't know if it is possible to do.
Someone can help??

Please explain more: how the vectors are connected? Can you attach some picture or data?

okay, sorry. Let's make an example:
x = [1 2 3]
y = [4 5 6]
z = [7 8 9]
phi = [0 30 0]
delta = [1 3 5]
x, y, z and phi represent the coordinates of 3 points, and delta their characteristics. For example, the point [x,y,z,phi] = [1,4,7,0] has characteristic delta = 1.
I'm searching for a way for rapresents the 3 points and their respective characteristics as a surface, where the colour represents the caracteristic of each point on this surface.
Hoping it is more clear, I'm sorry, it is my fault.

Just use griddata to interpolate data
Delta is represented by color.
x = 20*rand(100,1)-10; % surface coordinates
y = 20*rand(100,1)-10;
r = hypot(x,y);
z = -r.^2/10;
delta = sin(r); % surface color (characteristic)
xx = linspace(min(x),max(x),50);
yy = linspace(min(y),max(y),50);
[X,Y] = meshgrid(xx,yy); % create a mesh
Z = griddata(x,y,z,X,Y); % interpolate Z coord
D = griddata(x,y,delta,X,Y);% interpolate delta
scatter3(x,y,z,25,delta,'filled')
surface(X,Y,Z,D,'facecolor','interp')
axis equal
colorbar
