Hard Constraints

[Emmanuel Iarussi]

Is there a way to impose hard constraints on my problem using Ceres? I would like to enforce C1 continuity in an interpolation problem. Thanks!

What problem are you trying to solve?  What do you want to enforce C1 continuity on?

The usual way to address this is via the parameterisation of the model you are trying to fit.  If you want the model to be C1 for example, then you can easily enforce this by using a (>= quadratic) B-Spline as your underlying model, with the parameter blocks in the Ceres problem corresponding to the control points of the B-Spline.
