Well, no, I don't know a free library that does that.

I suspect your needs are very specific, that is, not everybody has those needs. Therefore, you probably won't find any ready-made functions for this.
You might also consider using other data structures, instead of arrays - for example, cursors, which are simply temporary tables. For example, Visual FoxPro's arrays are limited to 1 or 2 dimensions; I published a download here on the Universal Thread of an "array" that permits many more dimensions. The data is internally stored in a cursor.
