expmualambda
Expmualambda is a term used in mathematical and computational contexts to denote a parametric exponential map applied to a linear operator, combining two scalar or matrix parameters often denoted μ and λ. It is not a standard term with a unique universal definition; different sources may adopt different conventions.
A common interpretation treats expmualambda as the matrix exponential of a scaled operator: expmualambda(A, μ, λ) = exp((μ λ) A),
Computation follows standard matrix-exponential techniques: scaling and squaring with a Padé approximation, or eigenvalue decompositions when
Applications include solving linear differential equations with time-dependent or parameter-dependent operators, modeling continuous-time Markov processes with
