comment export data points from differential equation system?
No need to load that package, even, since it's just a front end for hidden built-in functionality. f["Coordinates"] (where f[] is the InterpolatingFunction[] object) does the job.

comment Is Mathematica matrix multiplication with its inverse wrong?
The OP's confusion might be due to the fact that in MATLAB, * performs matrix multiplication, while .* performs Hadamard multiplication. In Mathematica, OTOH, * is Hadamard multiplication, while . is the operator for matrix multiplication. Common trip-up...

comment How do I find an equilateral triangle whose vertices have integer coordinates?
See this math.SE question. As noted there, in 3D, you can have an equilateral triangle with integer coordinates (it is easy to construct an octahedron with integer coordinates, and its faces are equilateral triangles); in 2D, this is impossible.
