i have an array a=[102, 2,3,201,8,9]
so when i convert it to binary each term has same length as
[ 0 1 1 0 0 1 1 0
0 0 0 0 0 0 1 0
0 0 0 0 0 0 1 1
1 1 0 0 1 0 0 1
0 0 0 0 1 0 0 0
0 0 0 0 1 0 0 1]
but i want each term to become binary according to the size not with padded zero as 2 in binary is '10' not '0 0 0 0 0 0 1 0'
thanks in advance

Numeric only
Sorry, that is not possible in MATLAB. In MATLAB, numeric arrays must always have the same number of columns in each row.
If you had wanted cell array of character vectors, or string array, or cell array of numeric vectors, then those would be possible.

Cell array of character vectors:
>> a = [102,2,3,201,8,9];
>> c = arrayfun(@dec2bin,a,'uni',0);
>> c{:}
ans = 1100110
ans = 10
ans = 11
ans = 11001001
ans = 1000
ans = 1001
Cell array of numeric vectors:
>> c = arrayfun(@(n)dec2bin(n)-'0',a,'uni',0);
>> c{:}
ans =
1 1 0 0 1 1 0
ans =
1 0
ans =
1 1
ans =
1 1 0 0 1 0 0 1
ans =
1 0 0 0
ans =
1 0 0 1
