I have
tbl2 = 1*1 cell array
{[1.29]}
Name Size Bytes Class Attributes
tbl2 1x1 112 cell
How can one extract a double from this cell array?

value = tbl{1} % Extract 1.29 from the cell
I think you should really read the FAQ so you get a good intuitive feel for how to use cell arrays and when to use braces, brackets, and parentheses:

Basic cell array indexing (as Image Analyst showed) is the simpler, efficient, correct approach. Using CELL2MAT is unnecessarily slow and complex for this trivial task.
