chsolve — sparse Cholesky solver
sol=chsolve(spcho,rhs)
list containing the Cholesky factors in coded form returned by chfact
full column vectors
sol=chsolve(spcho,rhs)
computes the solution of
rhs=A*sol
, with A
a symmetric sparse positive definite
matrix. This function is based on the Ng-Peyton programs (ORNL). See the
Fortran programs for a complete description of the variables in
spcho
.
