Surf plot error for 4 variable input

I have the following set of vectors, generated from a data set, each a length of 15120
Min/Max
x 0/1
y -3.5/1
z 25/220
v 0/0.8464
end
For each vector, each row represents a unique data point.
I think Im pretty much using the standard script for interpolating a surface between the data points;
if true
z=S2(:,1);
y=S2(:,3);
x=S2(:,4);
v=S2(:,2);
[xq,yq,zq]=meshgrid(0:0.05:1, -3.5:0.225:1, 25:9.75:220);
vq=griddata(x,y,z,v,xq,yq,zq);
surf(vq,zq,yq,xq);
end
this generates 21x21x21 grids for vq,xq,yq,zq which obviously dont work :(
In summary I really wish to plot a surface of V with respect to the three other variables. Any advice would be great. Thanks

Firstly, matlab will probably struggle to plot matrices with dimensions of 15120.
Second, need to clarify: x,y,z are coordinates? how does v depend on x,y,z seperately?
Finally, what is S2?

Hi William, sorry for not getting back to you sooner. S2 is a 4x15120 variable from which I extract all of the other variables. So I ran simulations, whereby I vary x, y and z as independent variables and get a resultant variable of v. I covered all of the parameter space such that a 3x3 block is sampled everywhere.

if you could upload the data that would be helpful
