Jc. Jimenez et al., COMPUTING THE NOISE COVARIANCE-MATRIX OF THE LOCAL LINEARIZATION SCHEME FOR THE NUMERICAL-SOLUTION OF STOCHASTIC DIFFERENTIAL-EQUATIONS, Applied mathematics letters, 11(1), 1998, pp. 19-23
An algorithm is given that computes the covariance matrix of the noise
term of the local linearization scheme for the numerical integration
of stochastic differential equations. The order of convergence of the
resulting approximation is studied. An example is presented that illus
trates the performance of the algorithm.
