When you make a tall array from a fileDatastore, the resulting tall array is a tall cell array. CELL2UNDERLYING converts that tall cell array to a tall array of the underlying data. For example, if your fileDatastore returns a table for each file that it reads, then a tall array based on that fileDatastore would be a tall cell array where each cell contained a table. Using CELL2UNDERLYING would convert that to a tall table.

This update introduces a second syntax of CELL2UNDERLYING that allows you to provide an example of the underlying data. This is useful when you need to use CELL2UNDERLYING on the output of expensive tall calculations.
