Julia reimplementation of Total Variation Regularized Numerical Differentiation (TVRegDiff).

Based on Rick Chartrand's original Matlab code and Simone Sturniolo's Python reimplementation.


TVRegDiff works on noisy data without suppressing jump discontinuities

TVRegDiff also works on large datasets

More examples can be found in the documentation.


To install this package and its dependencies, open the Julia REPL and run

julia> ]add NoiseRobustDifferentiation

Julia 1.5 is required.
