-----------------------------------------
|

|
||
1. Add ULK_matrix.c and ULK_vector.c to your source files.
|
||
2. Add ULK_matrix.h to your include files.
|
||
3. Edit ULK_matrix.c, l.44 to match the path to ULK_matrix.h.
|
||
4. Edit ULK_vector.c, l.43 to match the path to ULK_vector.h.
|
||
|
||
Linker options: None, unless your plattform treats math.h as a library, then add -lm (eg. Linux).
