Visualisation of Vector Function on Convex Set

Vector function transforms set D into set S. Here set D is assumed to be convex and to be a solution of linear inequalities system. You can change the RHS parameters (sliders b1, b2, b3, b4) in linear inequalities system and the parameters of vector function (c11, c12, c21, c22). Look how all this changes influence set D and set S. Vector functions have economic application e.g. as in multicriteria linear programming (see another applet).
