Ive created a matrix of velocities for various positions along a square section in 3d. I would like to plot these velocities preferably with colours showing the velocity at each position, how would I go about doing this?

You can mesh or surf

The matrix is a 3d matrix of size 100x100x200 so surf or mesh wont work. Id like a plot of size 100x100x200 with each node having a colour relating to its velocity.

doc isosurface
doc patch
and perhaps
doc quiver3

None of these work. I effectively want a scatter graph with the coordinates being the i,j,k of the points in the matrix and their colour being the value of the matrix at i,j,k.

so scatter3 should work.
