How do I name elements in a field of a structure?

I have a 1*1 structure with 4 fields. The structure was generated from anova1 so I didn't create it. One field is 33 *2 and I want to name each integer place with a string but I cannot seem to do this. Can anyone help?
Thanks! Kim

Okay, now what is it you want to do with the information?
It appears to me that if you want to know the group name for the group whose mean is st.means(K) then you would find it at st.gnames(K,:)

A=struct('a',rand(33,2),'b',1,'c',2,'d',3) % your struct array
v=A.a
B.b=A.b
B.c=A.c
B.d=A.d
m=0
for k=1:33
for p=1:2
m=m+1
B.(sprintf('a%d',m))=v(k,p)
end
end

I'm not sure what you mean by naming each integer place with a string?
You can use
Structurename.appropriate_fieldname(I,J)
to access at matrix location (I,J) of the field. You can use
fieldnames(Structurename)
to find out what the field names are.
You cannot, however, do something like say that you want the variable "PLU" to refer to column 1 of the field -- not without extracting it from the structure.
If you need to be able to say things like "PLU(5) = 142031" and have it affect the contents of the structure field, then you need to use a "dataset", which I seem to recall is part of the Stats toolbox.
