Is there a function like [deval](https://uk.mathworks.com/help/matlab/ref/deval.html) in DifferentialEquations.jl?

If what you are after is controlling which points the solution is saved at, there is a `saveat` keyword argument for the `solve` method.
See e.g. [Getting Started with Differential Equations in Julia ยท DifferentialEquations.jl](https://docs.sciml.ai/DiffEqDocs/stable/getting_started/#Controlling-the-Solvers) for example usage.

Fantastic, thanks. This is exactly what I wanted.
