Simslope Initial commit. e9ccd3d49b4b1342341f1866a3f7a941af503b30 Josiah_Mullins_Optiplex_Mini 2019-12-01 21:24:04
Commit 707e5be5af137023c28c12d54af35394cc32c9cc - simslope.c: type change
This commit changes the type of rand_j and rand_k from
type int to type unsigned char. All neccessary changes
to the alogrithms were also done. In the function main,
the unused variable i was removed and some ambiguous
code was clarified.
