chsolve sparse Cholesky solver sol=chsolve(spcho,rhs) spcho list containing the Cholesky factors in coded form returned by chfact rhs, sol 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. chfact sparse lufact luget spchol
