Make a collection function space

Collection function spaces. The interface and object storage model is experimental and may change.

Usage

fm_collect(x, ...)

Arguments

x

list of function space objects, such as fm_mesh_2d(), all of the same type.

Value

A fm_collect or fm_collect_list object. Elements of fm_collect:

fun_spaces

fm_list of function space objects

manifold

character; manifold type summary, obtained from the function spaces.
