You can use reshape()
reshape(Radiatondamping(1,:), 6, 6).'
the above will convert first column to 6x6 matrix. To convert all columns and combine them in 3D matrix
permute(reshape(Radiatondamping.', 6, 6, []), [2 1 3])

Here's one way (tested on made up "data"):
data = randi(99, 12, 6)
[rows, columns] = size(data)
newRows = rows / 6 % This better be an integer!!!
d = data'
Radiatondamping = reshape(d(:), [], newRows)'
