IML - Integer Matrix Library
IML - Integer Matrix Library. IML is a free library of C source code which implements algorithms for computing exact solutions to dense systems of linear equations over the integers. IML is designed to be compiled with a CBLAS library (e.g., ATLAS/BLAS) and the GMP bignum library. Written in portable C, IML can be used on both 32-bit and 64-bit machines. It can be called from C++. Currently, IML provides the following functionality: Nonsingular rational system solving: compute the unique rational solution X to the system AX=B, where A and B are integer matrices, A nonsingular. Compute the right nullspace of an integer matrix. Certified linear system solving: compute a minimal denominator solution x to a system Ax=b, where b is an integer vector and A is an integer matrix with arbitrary shape and rank profile. In addition, IML provides some low level routines for a variety of mod p matrix operations: computing the row-echelon form, determinant, rank profile, and inverse of a mod p matrix. These mod p routines are not general purpose; they require that p satisfy some preconditions based on the dimension of the input matrix (usually p should be prime and should be no more than about 20 bits long).
