4-D plot in Matlab

I have 4 vectors of size 50. How can I plot them in 4-D in Matlab. I tried "surf". But Matlab gives me an error "Z must be a matrix, not a scalar or vector."

For vectors v1, v2, v3, and v4, you can plot the first three vectors as x,y,z locations and v4 as color with

scatter3(v1,v2,v3,30,v4,'filled')

The 30 scales the marker size.

Thank you. It works.
