It is an upper bound for the L2 norm of the Cauchy error expm (x, *, order + 10) - expm (x, *, order). The exponential of a matrix is defined as the infinite Taylor series expm (A) = I + A + A^2/2! + A^3/3! + (although this is definitely not the way to compute it). The method for the dgeMatrix class uses Ward's diagonal Pade' approximation with three step preconditioning.

pow = function(x, n) { if (n == 0) { I <- diag(length(diag(x))) return(I) } Reduce(`%*%`, replicate(n, x, simplify = FALSE)) } where xis the vector underlying the R matrix and nis the number of lines (or columns) of the matrix. The matrix exponential is returned in z.

Several methods are provided. The Taylor series and Padé approximation are very importantly combined with scaling and squaring. The package contains an R interface and a C API that package authors can use.
