Real and complex functions form the backbone of modern mathematical analysis, uniting the study of continuity, differentiability, and integrability on the real line with the rich structure of analytic ...

Applications of Fréchet derivative emerge in the sensitivity analysis of matrix functions. Our work extends the generalized complex step approximation using the complex computation f(A + eiθhE) as a ...

Have you ever thought of the humble SUM function as a secret weapon for advanced analytics? Most Excel users see it as a basic tool for adding numbers, but what if I told you it could do so much more?
