Re: manipulating data

["Zé Pedro" <zarroba@...>]

Well, I had a similar problem in my application and what I did was to create a Matrix c++ object that I exported to Lua. So you could do something like:

matrix = getMatrix("name");
objs = matrix:getObjectsByType("type"); 

for example. I don't have here the code I've made but tell if it is something like this that you want that I'll send it to you tomorrow.

In my application I have a matrix of data for which I want to use Lua to
manipulate it. I'm planning to implement filtering functions, statistical
functions and the like.
What I'm still struggeling with though is how to represent the data in Lua.
Currently I'm planning to keep the data in my app and provide getters and
setters for the data. I'm finding difficulties though to find a proper
description of it in the PIL or refman. But afair there should be a
possibility to do it.

So what I want to be able to do is:

data[1,2] = 1.234
print(data[1,2])  -- returns 1.234

Can someone point me to the right resources so I can start reading and
testing myself? Or perhaps someone can give me a hint.
