title: What Android packages are available for vector, scalar, matrix, and FP math?
body: <p>What packages are suggested to perform complex math operations like vector multiplication, vector conversions(int to FP), etc. on the Android platform.  It does not look like java.lang.math is stout enough.  It has been suggested I look into the NDK and a good c/c++ lib or siglib.  Are there any other suggestions? Thanks...</p>
