I'm reading through a file and want to create a map of string keys, each with an array of numeric arrays. How do I go about declaring this object and then appending arrays to the values?

If I understand well what you are trying to achieve, you can:
  • Build your own system using a cell array of keys and STRCMP/STRCMPI/REGEXP for matching key/value pairs.
  • Use a containers.Map object.
  • Use a Java Hashtable object ( java.util.Hashtable )
Note that if you need to store complex data structures, a good option is to use a hybrid approach, where you define a values cell array, a keys hashtable, and then store complex data structures in the cell array and only their IDs in the hashtable.

Eh, in the end it was easy enough just to save the relevant information to files with Python, then process it further in Matlab.
