These are the MATLAB versions of the functions used in the book Fundamentals of Numerical Computation by Tobin A. Driscoll and Richard J. Braun. There have been some implementation changes since the print edition of the text.
-
hatfunnow returns a callable function of$x$ rather than requiring the evaluation points at the time of construction. - The IVP solvers use MATLAB's new IVP structure to set up the problem. This makes it potentially less confusing to pass parameters into the ODE function.
- The boundary conditions of a BVP in Chapter 10 are specified a little differently.
- There is a
tensorgridfunction that creates several values and functions useful to the discussion and algorithms of Chapter 13. - The
newtonpdefunction has been replaced by a more generalellipticfunction to solve an elliptic PDE on a rectangular domain.
