[petsc-users] SNES for 1D problem?

[Adrian Croucher]

hi

If part of my code needs a one-dimensional nonlinear solver (i.e. to 
solve for a single scalar variable), which for some problems will be 
called many times, does it still make sense to use SNES for that? or are 
there overheads from the vector machinery that make it less efficient 
for that case than rolling your own simple solver?
