Dear friends

I solve a rectangular system of equations AX=B   where A from order 3m+1x2m      X from order 2mx1       B from order (3m+1)x1   where  m=400, by LeastSquare or by multiply by A^T  

A^T*A*X=A^T*X

let M=A^T*A

then     M*X=A^T*X                 finally               X=M^-1 * A^T*X

by a message appears  "the memory is not enough"

where the memory is 2 Gigabytes.

Also, by increase the virtual memory for the drive C and D.      The problem is still found
