How to import a csv file into a matrix

[Mohamed1234]

I have to import data points, x and y values for a curve. The data must be placed in separate matrices and matrix operations must be performed (transpose,inve rt and multiplication) to the matrices. I managed to place the data into a list using the append function Ina while loop, but lists can't be used for the algebra. So I would like to know if there is a way to place the data in a matrix without downloading extra modules.

Place the data in an array ?
Is it possible to attach your code and data so we can work on the same data and structure?

What exactly is a matrix? In VB terms, I mean.
