mapObj = containers.Map({key1, key2, ...}, {val1, val2, ...});

For those keys and values that are character vectors, be sure that you specify them
enclosed within single quotation marks. For example, when constructing a Map that has
character vectors as keys, use

mapObj = containers.Map(...
{'keystr1', 'keystr2', ...}, {val1, val2, ...});

As an example of constructing an initialized Map object, create a new Map for the
following key/value pairs taken from the monthly rainfall map shown earlier in this
section.
