>> clear
>> a=1; b=2; c=3;
>> s=whos;
>> C=cell2struct({s.name}.',{s.name})
C =
a: 'a'
b: 'b'
c: 'c'
>> structvars(C,0); %copy/paste the output below to the command line
ans =
C.a = a;
C.b = b;
C.c = c;

s = struct('alpha', alpha, 'beta', beta, 'gamma', gamma);
doc struct

You could dynamically create a structure with 30 field names that are the names of the variables, however I would urge to think whether it's really what you want. How are you going to then use that structure if the field names are created arbitrarily. I would advise against this as your code may easily break in the future because a hardcoded field is not there anymore.
If that's really what you want to do, then structvars from the other answer (you have to download it), or the following function will do it:
function s = variables2struct(varargin)
s = struct;
for var = 1:nargin
s.(genvarname(inputname(var), fieldnames(s))) = varargin{var};
end
end

myStruct.alfa = alfa;
myStruct.beta = beta;
etc.
Or
myStruct = struct( 'alfa', alfa, 'beta', beta );

I could try to give some help further along this line, but I think potentially either of Matt J's solutions would work better so unless neither of them do I'll leave it.
