How do I extract a 256x256 matrix from a 1x1 cell?

Using an augmented image datastore, I reading a single image and the output looks like this. When I use the table2cell function, the new image has a strange output and not the matrix I was expecting (only 1x1!). How do I produce the 256x256 matrix of values that I am looking for?

If you didn't want a cell, shouldn't call a function ending in "2cell"! :)

For a 1-element table,

img=table2array(oldimage);

will work...if there's more than one array in the table, however, this will merge all into a single array.

Can't see what the variable name is in the original table, but dereference the table by

img=tablename.variablename;

will return the data in its original storage form for the one variable
