I have a matrix: A(16,24,336). How can I plot this A matrix in 4D? The A matrix is based off the following matrices: D(16,1), T(1,24), and L(336,1). How can I plot D, T, L with the color representing the A values? Or just how could I plot this data in general? I am very new to Matlab and would appreciate as detailed explanation as possible.

look at the documentation for

slice

by typing in the command window

doc slice

also, look at the documentation for

meshgrid

I think that I have an answer. I have achieved this with the data in a slightly different format

Essentially I had a file that gave me

x0, y0, z0, c0 x0, y1, z0, c1 x0, y2, z0, c2 . . . . . . . . . x1, y0, z0, c_n x1, y1, z0, c_n+1 . . .

To plot these I use the reshape command:

xq = reshape(x,137,19)

where the 137 is total number between repeats in the x and y, and 19 is the total number of time the pattern repeats, AKA the depth slices.

The reshape command leaves me with 4 137x19 matricies that I called xq, yq, zq, cq. You can then use the surf command to plot your data:

surf(xq,yq,zq,cq)

I hope this helps! I am still trying to figure out how to interpolate my values to a finer mesh.
