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?

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.
