I construct a Lanczos process on a large and sparse matrix and use the
results of this iteration to compute the inverse square root of the same
matrix. The algorithm is a stable version of an earlier proposal by the author.
It can be used for problems related to the matrix sign and polar decomposition.
The application here comes from the theory of chiral fermions on the lattice.
