How to decode a cell type variable to a decimal?

I want to implement this function:

power =3+ sqrt(das.*das);

But das is cell type (with binary digits) so when I run the "power" function I get an error:

Undefined operator '.*' for input arguments of type 'cell'.

So I want to decode the cell type variable das to a decimal so that the function can run properly. How do I do that?

Das= cell2mat(das);

power =3+ sqrt(Das.*Das);
