Create a 4D Horace dataset ('d4d')
Syntax:
>> w = d4d (filename) % Create object from a file
>> w = d4d (din) % Create from a structure with valid fields
% Structure array will output an array of objects
Or:
>> w = d4d (u1,p1,u2,p2,u3,p3,u4,p4)
% u1,u2,u3,u4 vectors define projection axes in rlu,
p1,p2,p3,p4 give start,step and finish for the axes
>> w = d4d (u0,...) % u0 is offset of origin of dataset,
>> w = d4d (lattice,...) % Give lattice parameters [a,b,c,alf,bet,gam]
>> w = d4d (lattice,u0,...) % Give u0 and lattice parameters
Input parameters in more detail:
----------------------------------
lattice Defines crystal lattice: [a,b,c,alpha,beta,gamma]
u0 Vector of form [h0,k0,l0] or [h0,k0,l0,en0]
that defines an origin point on the manifold of the dataset.
If en0 omitted, then assumed to be zero.
u1 Vector [h1,k1,l1] or [h1,k1,l1,en1] defining a plot axis. Must
not mix momentum and energy components e.g. [1,1,2], [0,2,0,0] and
[0,0,0,1] are valid; [1,0,0,1] is not.
p1 Vector of form [plo,delta_p,phi] that defines limits and step
in multiples of u1.
u2,p2 For second plot axis
u3,p3 For third plot axis
u4,p4 For fourth plot axis
