Invert a matrix larger than 52 x 52 using MINVERSE

[Guest]

I have been using Excel (Office 2000) at work for several years which
involves matrix inversion and Visual Basic. I have found that the largest
matrix that can be inverted is 52 x 52. I need to invert larger matrices,
100 x 100 would be better; 150 x 150 would be much better. Are there plans
to allow this in future Excel versions. I am using the MINVERSE function.

I've not used these functions, but Longre's free morefunc.xll add-in, available
at http://xcell05.free.fr/ has included in it matrix functions that do not have
the size limitation of Excel.
