X{1,1}(1)
- () parentheses always return the cell or element of the same class.
- {} curly braces always refer to the cell contents of a cell array.
Which means:
X{1,1} <- extract contents from the cell array X
(1) <- refer to first element of extracted data
The title "Can't get cell value" and your attempts to access this data indicates a misunderstanding of cell arrays. Cell arrays do not have numeric values, they merely contain other arrays. Your data is in a numeric array inside a cell array, so to access any numeric value you need to "remove" the numeric array from the cell array using {}... and it can then be indexed normally using ().
