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.
