Hi,

I need to be able to produce the inverse of a 2d array in java. Similarly to the excel function 'MInverse' (Application.WorksheetFunction.MInverse(z)) where z is double[][] z = new double[x][x];

please help.

This from UNLV is supposed to be along the same lines, so you may be able to learn from this approach:
