Simplest solution: Check the returned value by gnsSolveByChol(). If the return value indicates a singular case then assign filter coefficients arbitrarily #ifndef MOT_SPARSE_FIX gnsSolveByChol(E, y, filterCoeff, sqrFiltLength); #else int singular = gnsSolveByChol(E, y, filterCoeff, sqrFiltLength); if(singular == 0) { filterCoeff[0] = 1; for (i=1; i
