function D1=TEST()
D=readtable('test.txt','delimiter',',');
save canc.tset D
D1=load('canc.tset',"-mat")
end
i access it using
D1.D...
it's possibile to avoid "D" field?

It doesn't. READTABLE has nothing to do with the scalar structure returned by LOAD.

If there is only one variable in the MAT file (regardless of its extension) and you do not know/care what its name is:
C = struct2cell(load(..));
assert(isscalar(C),'Only one array can be LOADed')
T = C{1}
If the variable name is known in advance, e.g. "D"
S = load(..)
T = S.D

save('prova.txt','T')
SAVE is an exception: it requires the name/s of the variable/s that you want to save, not the variables themselves. That is explained and shown in the SAVE documentation. You should look at the documentation of every function that you use.
