Just use indexing:

out = inputdlg(...);
somevar  = out{1};
othervar = out{2};
...

Yes, values are assigned to variables but, I am getting error when I use these variables in formula. Error: undefined operator '+' for input arguments of type 'cell'

@Sachin Dighe: inputdlg returns character vectors in a cell array, not numerics. It is not clear to me what you expect to get by using + on some cell arrays.

If you want numeric values, then you will need to convert the character vectors to numeric, e.g. using str2double or sscanf or the like:

>> out = inputdlg({'A','B'});
>> A = str2double(out(1));
>> B = str2double(out(2));
>> A+B
ans =
          7.3

Note that this issue is unrelated to your original question and my answer, so it is unclear why you have unaccepted my answer (which correctly answered your question).
