In general, the answer to your question is no. Even for a R --> R
function, there is no Maxima function that will find all the local
minima (either symbolically or approximately). For example, find all
local minima for the function x |--> bessel_j(0,x). Maxima doesn't
even have an effective way to represent nonfinite sets.
Maybe you are looking for a function that finds floating point
approximations to local minima that doesn't always give up after
finding just one local minima. I don't know of a Maxima function that
can do that either.
