How to get value from nested table?

I run this command boundaryindx{dtbung,2}(1,1) and get this result [230.605758582503]. How if I want the result is only 230.605758582503, not [230.605758582503]?

boundaryindx appears to be a cell array. To convert to a number, one way is,

cell2mat(boundaryindx{dtbung,1}(1,1))
