I need to calculate derivative of the following function of X with respect to X: $\displaystyle f(X)=||diag(X^TX)||_2^2$ where $\displaystyle diag()$ returns diagonal elements of a matrix into a vector. How can I calculate $\displaystyle \frac {\partial f(X)} {\partial X}$? Please help me. Thanks in advance!
