Standard Kaczmarz not accepting enforcePositive and enforceReal

[jonschumacher]

Due to the interface changes, the standard Kaczmarz not accepting enforcePositive and enforceReal as keyword arguments anymore. The DAXKazmarz still accepts the keyword arguments and adds the regularizers in

RegularizedLeastSquares.jl/src/DAXKaczmarz.jl

Lines 74 to 79 in 94d2bf6

	reg = AbstractRegularization[]
	if enforcePositive && enforceReal
	push!(reg, PositiveRegularization())
	elseif enforceReal
	push!(reg, RealRegularization())
	end

. I would simply go for the same way if it weren't for

RegularizedLeastSquares.jl/src/Kaczmarz.jl

Line 79 in 94d2bf6

error("Kaczmarz does not allow for more than one additional regularization term, found $(length(reg))")

. Thus I am not sure how to fix this issue.

The DAX solvers as well as PrimalDual are not up to date.

The keywords have been removed and instead one has to supply the proximal terms for positivity and real number constraints. Kaczmarz accepts currently an arbitrary number of projection terms so those will not run into that error case.

MPIReco translates the respective enforceX kwargs into the proximal maps during the LeastSquares-process call

Thanks for the clarification! For the record: use reg=[L2Regularization(λ), PositiveRegularization()] when creating the solver and it works. I just misunderstood the code.
