Coefficient functions in linear differential systems are often required to be strictly
positive. This can be achieved by defining the coefficient function to be the
exponential of a functional data object, and using this as the user-defined coefficient
fun$fd that evaluates the coefficient.
fun.explinear(tvec, bvec, Bbasisobj)
A vector of times at which the function is to be evaluated.
A vector or a single column of coefficient values for the functional data object.
A functional basis object.
The length of argument
bvec must match the number of basis functions in
A numeric vector of the same length as that of argument
the exponentials of the values of the functional basis object.
