b =
1×1 cell array
{1×2 cell}
i want to get last element in cell ("4") and convert it in double

Use indexing -
%Assuming this is how your data is stored
b = {{6,4}}
b = 1×1 cell array
{1×2 cell}
c = b{1}{2}
c = 4

Hi!
Use patentheses () if you want the output to be a cell
myCell = {42, rand(5)}
myCell = 1×2 cell array
{[42]} {5×5 double}
ele = myCell(1,2)
ele = 1×1 cell array
{5×5 double}
Use curly parentheses to get data from the cell in its type
ele = myCell{1,2}
ele = 5×5
0.5062 0.9224 0.3035 0.3201 0.1839 0.8434 0.3387 0.2509 0.9461 0.0362 0.7808 0.7764 0.8302 0.8172 0.1848 0.4092 0.3476 0.0203 0.6906 0.3348 0.1126 0.0982 0.7486 0.7783 0.4946
You can also try cell2mat with the first approach to convert cell to array of double..
myCell = {42, rand(5)}
myCell = 1×2 cell array
{[42]} {5×5 double}
ele = cell2mat(myCell(1,2))
ele = 5×5
0.8558 0.6122 0.0712 0.3533 0.1033 0.5384 0.4733 0.2903 0.4612 0.7655 0.9834 0.4619 0.2614 0.7796 0.3795 0.4509 0.1652 0.7384 0.5678 0.7921 0.8444 0.0822 0.0433 0.8701 0.6699
