 Construct a linear map object, either from an existing `LinearMap` or `AbstractMatrix` `A`,

+from a function or callable object `f`. In the latter case, one also needs to specify
 the size of the equivalent matrix representation `(M, N)`, i.e. for functions `f` acting
 on length `N` vectors and producing length `M` vectors (with default value `N=M`). Preferably,
 also the `eltype` `T` of the corresponding matrix representation needs to be specified, i.e.
