The goal was also to "clean up" the matrix and vector implementations.
I'd rather suggest to add such features in the "MathArrays" class:
-----
public static double[] ebeDivide(double[] numer,
double[] denom) {
if (numer.length != denom.length) {
throw new DimensionMismatchException(numer.length, denom.length);
}
final double[] result = numer.clone();
for (int i = 0; i < numer.length; i++) {
result[i] /= denom[i];
}
return result;
}

What do you think?
