In the previous section, we provided an overview of solving nonlinear equations. Here, we will focus on specific capabilities of our package NonlinearSolve.jl. Let’s cover the typical workflow of using NonlinearSolve.jl. First, we define the nonlinear equations. We will use a mutating function to compute our residual value from 𝑢 and 𝑝 and store it in F.
\
\ In Julia, mutating function names are appended with a . ! as a convention. Next, we construct a NonlinearFunction – a wrapper over f! that can store additional information like user-defined Jacobian functions and sparsity patterns.
