The c S nstant parameter, involves the spectra2 bounds of some matrices and can be obtained in O(N ) sine function evakations, where I/N is the discretization mesh size. It is shown that this parameter can be chosen in a stable manner in O(l) operations per iteration, if it is a22owed to vam with th
