Use of @property decorator in deconv.py

[kaghi]

Can I ask what the function of the property decorator is for a number of diff matrices defined under the DeconvBin class?

@property
    def scale(self) -> float:
        """Current scale value (delegated to solver)."""
        return self.solver.scale

    @property
    def H(self):
        """Convolution matrix H."""
        return self.solver.H

    @property
    def R(self):
        """Resampling matrix R."""
        return self.solver.R

    @property
    def R_org(self):
        """Original (full) resampling matrix."""
        return self.solver.R_org

    @property
    def nzidx_s(self):
        """Nonzero indices for s."""
        return self.solver.nzidx_s

    @property
    def nzidx_c(self):
        """Nonzero indices for c."""
        return self.solver.nzidx_c

    @property
    def coef(self):
        """Coefficient kernel."""
        return self.solver.coef

    @property
    def err_wt(self):
        """Error weighting vector."""
        return self.solver.err_wt

    @property
    def wgt_len(self):
        """Error weighting length."""
        return self.solver.wgt_len

is the question what is the @property decorator generally? or what is it being used for here

What it's being used for here

looks like it's just forwarding access for convenience so you can do self.R rather than self.solver.R - whether that's good or not is a design question. can be good when one is expected to access those attrs frequently/they should behave as if they come from that class. otherwise it doesn't really add much. keep them if they make the code clearer, ditch them if they don't, they shouldn't have any functional consequence
