Derivative of cross-product of two vectors with respect to vector

634 Views Asked by At

$\omega$ is a 3×1 vector and $I$ is a constant 3×3 matrix. What is the derivative respect to vector $\omega$? It would be appreciated if you could show me any references I can refer to. $$\frac{d(\omega \times I\omega)}{\omega}=?$$

Add $\varepsilon$ times a basis vector and look at the terms with a single $\epsilon$. That will be the corresponding column of the derivative matrix.
