Finding the derivative of a vector function is a fundamental concept in calculus that extends the idea of differentiation from scalar functions to functions that output vectors. This process is ...

This note studies the optimality conditions of vector optimization problems involving generalized convexity in locally convex spaces. Based upon the concept of Dini set-valued directional derivatives, ...

It uses a recursive function to calculate a finite differentiation aproximation of a given vector. This MATLAB code uses a recursive function DDF to calculate the finite derivative difference of a a ...

For a function f: x -> y, the Jacobian function has the signature: jac_f: x, out_y -> dy/dx. This signature makes a lot of sense in some situations. For example, if f is an implicit function, passing ...
