After reading a number of posts by fellow users recommending free mat, I decided to give it a go and I am really impressed.
One thing I find extremely useful in any programming language is a "dictionary" data type as it is referred to by python. Essential, it is very similar to an array but instead of indexing it via a simple integer that corresponds to the row/column of the value, you use a "key" value.
Matlab has implemented this (poorly) using the container.Map function. I am wondering if any such function exists for FreeMat? I find it a very useful (and efficient) tool for when dealing with large amounts of data or when making a large amount of references to existing data.
