Hello PTC community, thanks for taking your time to check this post out. I dont know if mathcad can do this but im pretty sure it can for what Ive seen. I want to make the sum of multiplying a component of a vector with a component of a matrice in an especific column, then with the next component of the vector with the second row in the same column and so on. Details are attached in the document. Thanks for all!
PS. If you are familiarized with chemical engineering, the problem I want to solve is a multicomponent destilation tower with the rigorous method ( I think its the Amundson-Pointnen method)
