Hello all,

Is there any function/package in Julia that I could use to integrate one-dimensional arbitrarily-spaced data?

[NumericalIntegration](https://github.com/dextorious/NumericalIntegration.jl) has several options, but they require evenly spaced data.

Best,  
Santiago

[Trapz.jl](https://github.com/francescoalemanno/Trapz.jl) is supposed to work on irregular grids.

Also take a look at the spline packages that have integral options, such as [BSplinesKit.jl](https://jipolanco.github.io/BSplineKit.jl/stable/splines/#BSplineKit.Splines.integral) or [Dierckx.jl](https://www.juliapackages.com/p/dierckx).
