dictionary.keys
dictionary: k = keys (d)
dictionary: k = keys (d, format)
Return the keys.
k = keys (d) returns the keys of d as a
column array of the key type, in the order they were added. Keys of a
type that cannot be joined into one array, such as function handles,
are refused unless there is exactly one.
k = keys (d, format) returns them as above for
format 'uniform', the default, and as a column cell
array, each key in a cell of its own, for 'cell'.
format is matched in any case and by its first letters.
d must be configured.
