Multiply and Inverse 2D Arrays

[MagnusFox]

I need to multiply some big (possibly 1000 X 7) rectangular(2d) arrays, and also find the inverse of the resultant array... is there a VB function that I could easily do this with?

I THINK it would follow along the lines of:
multiply(double a[][],double b[][])
inverse(double a[][])

Any help is great.

I'm not familiar w/ them, but there is a library or so specifically from array manipulation.

There is never time to do it right but there is always time to do it over

I do not think two 1000 by 7 2D arrays qualify for matrix multiplcation.
See

The product of two matrices and is defined by
c(i,k) = a(i,j)*b(j,k)
where j is summed over for all possible values of i and k. Therefore, in order for multiplication to be defined, the dimensions of the matrices must satisfy
(n X m)(m X p) = (n X p).

Correction.
The product C of two matrices A and B is defined by
c(i,k) = a(i,j)*b(j,k)
