Dear all,

I have a big matrix (2000x2000) which every elements of my matrix is of the order of 1.0e12 and i want to compute its inverse. since the data are too big, IDL could not determine the matrix determinant (even with determ(A,/double) command) and return Inf. Is there a way to compute its inverse and determinant?

Cheers,
