n-D look up table editor - adding rows / columns

Hello,

I would like to ask if there is possibility to edit look up tables in n-D size (3-D in my case)?

I have matrice 9x5x6 and i need to put these data to the 3-D lookuptable.

For 2-D LUT i found that it is possible to add rows and columns, but not in n-D.

Is there any easy way how to create table from excel data?

Thanks for your help

It is possible to add new "slices" (i.e. 2D matrices) into a 3D array:

format compact
x = zeros(2,4,3)

x = 
x(:,:,1) =
     0     0     0     0
     0     0     0     0
x(:,:,2) =
     0     0     0     0
     0     0     0     0
x(:,:,3) =
     0     0     0     0
     0     0     0     0

new_slice = ones(2,4);
x = cat(3,x(:,:,1:2),new_slice,x(:,:,3))

x = 
x(:,:,1) =
     0     0     0     0
     0     0     0     0
x(:,:,2) =
     0     0     0     0
     0     0     0     0
x(:,:,3) =
     1     1     1     1
     1     1     1     1
x(:,:,4) =
     0     0     0     0
     0     0     0     0

That's a 2-by-4 matrix of all ones being inserted at index 3 in the third dimension of x. You can just as easily insert 2D matrices into a 3D array in any dimension, if the sizes are the same in the other dimensions.

Is this the kind of thing you're asking about?
