for j = 1:sz_idx1(1,1)
new_idx = idx1(j);
alt_i = alt{new_idx};
if ( alt_i== 'T')
A_T = count+1;
end
end

count = 0 ;
A_T = zeros([],1) ;
for j = 1:sz_idx1(1,1)
new_idx = idx1(j);
alt_i = alt{new_idx};
if ( alt_i== 'T')
A_T(count) = count+1;
end
end

Empty matrix: 0-by-1
Undefined function or variable 'count'.
Error in testrun (line 32) A_T(count) = count+1;
it shows this error

I though you have already define count before for loop..edited the answer.

Attempted to access A_T(0); index must be a positive integer or logical.
Error in testrun (line 31) A_T(count) = count+1;
i defined count before and it shows this error

Replace "A_T(count) = count+1;" by
count = count + 1;
A_T(count) = count;

What about:
A_T = cumsum(strcmp(alt{idx1}, 'T'))
instead of the loops? Or perhaps you want:
A_T = sum(strcmp(alt{idx1}, 'T'))
or
A_T = 1:sum(strcmp(alt{idx1}, 'T'))
