mc_dexp_gold: Exponential-matrix and its derivatives
In mcglm: Multivariate Covariance Generalized Linear Models
mc_dexp_gold R Documentation
Exponential-matrix and its derivatives
Description
Given a matrix M and its derivative dM the
function dexp_gold returns the exponential-matrix
expm(M) and its derivative. This function is based on the
expm function. It is not really used in the
package, but I keep this function to test my own implementation
based on eigen values decomposition.
Usage
mc_dexp_gold(M, dM)
Arguments
M
A matrix.
dM
A matrix.
Value
A list with two elements: expm(M) and its derivatives.
Author(s)
Wagner Hugo Bonat
See Also
expm, eigen.
Examples
M <- matrix(c(1,0.8,0.8,1), 2,2)
dM <- matrix(c(0,1,1,0),2,2)
mcglm::mc_dexp_gold(M = M, dM = dM)
