Hello. I tried to write implement a Gauss-Seidel Method, but got an error. I initialised all variables and wrote all the programming, which seems to be alright, but when I am trying to assign an element of previously initialised vector to a variable, it throws a "This value must be a vector" error. I have no idea why this is like that, I googled the manual about matrices and vectors and it says that Mathcad must recognise 3x1 matrices as column vectors.
Moreover, the same code works in Mathcad 15 flawlessly (I have no possibility of using a code convertor included in Mathcad Prime).
Any suggestions?
