~\\ The diffusion constant $c$ in \kwo{mat.mat}\texttt{(1)} is passed to the function \kwc{elm1d\_c} together with the integration point coordinate $x$. So the function \kwc{elm1d\_c} can be used to work with a coordinate dependent diffusion constant $c_\mathrm{int}(x)$ based on $c$:
function c_int = elm1d_c(c, x)
% c_int = elm1d_c(c, x)
% function to create a coordinate dependent diffusion constant
% See also elm1d, fem1d
if c < 0 % non-constant c
c_int = 1 + x;
c_int = c;
else % nothing to see here
c_int = c;
% part of mlfem_nac:
The default behavior of \kwc{elm1d\_c} is to use a constant value $c$ for \kwo{mat.mat}\texttt{(1)} $\geq 0$, and to switch to a coordinate dependent value otherwise. You can use a copy of this function (original in \kdir{/library/elmlib}) in your working directory to change this behavior. \\
