log10 and log2 are only special cases, but will be computed more efficiently and accurately where supported by the OS.. Value. A vector of the same length as x containing the transformed values.log(0) gives -Inf (when available). Note. log and logb are the same thing in R In R, matrix exponentiation is provided by the function expm, in the add-on package of the same name. (Note: The standard R exponential function, exp, will compute an element-wise exponential when supplied with a matrix argument.
The method for the dgeMatrix class uses Ward's diagonal Pade' approximation with three step preconditioning.
Notes on the matrix exponential Erik Wahlén erik.wahlen@math.lu.se ebruaryF 14, 2012 1 Introduction The purpose of these notes is to describe how one can compute the matrix exponential eA when A is not diagonalisable. This is done in escThl by transforming A into Jordan normal form. As we will see here, it is not necessary to go this far.
The routine uses the algorithm of Ward (1977) based on diagonal Padé table approximations in conjunction with three step preconditioning. The Padé approximation to eA is eA ≈R(A), with R pq(A)=(D pq(A Terry Therneau wrote: > Is the matrix exponential available in some package? Multiple.
