Hi Im trying to create a matrix X 250 cols and 1.6 million rows, and I want to compute inv(XX). Im using Intel Visual Fortran Compiler 11.0 with MS Visual Studio on a 64 bit system. Two questions:

  1. How do set I set fortran to handle a matrix of this size? Right now I'm getting the following error: "Error 1 fatal error LNK1248: image size (804D9000) exceeds maximum allowable size (80000000) LINK" or it just aborts when compiling (saying something cryptic like "code 3").

  2. is there an easy math function to invert the matrix?
Thanks for your help!

Use an ALLOCATABLE array. Even 64-bit Windows can't handle a static array that large.

The Intel Math Kernel Library has routines for doing matrix inversion. Look in the on-disk documentation index under "Inverting a matrix".
