This directory contains 5 files: README (The file you are reading now) obj.f Fortran source code for solving an ODE (see comments inside) Also in obj.f you may find the code for a single-hidden layer sigmoid perceptron with linear output node. (Identity) objnn.f Fortran code for solving the example of the same ODE, with Neumann conditions prescribed at both ends. PARA A file containing parameter statements needed in subroutines and functions contained in obj.f and objnn.f, used via "INCLUDE" statements. Neuman_to_Dirichlet.pdf A file describing in detail the theory behind the code.
