logm
Logarithm for matrix for itau object.
Syntax
F = logm(x, coef)
Description
F = logm(x) returns the F matrix suth that F is the Taylor series
expansion for function of matrices. Here is sused Malab's function
"logm" for our x propertie, it means, matrixM(x) = M.
Input (required)
x = independent tau variable (itau object).
Input (optional)
coef = coefficients of a polynomial (double vector).
If coef is informed, then we want log(sum[coef_iP_i(M)]).
Output
F = matrix sized by [x.n x.n], translating log(M) in terms of
its Taylor series expansion (double matrix in F.mat).
See also
sinm, sinhm, cosm, coshm, expm and sqrtm.
