Suppose that I want to solve symbolically a system of lienar equations defines as: $Ax=B$ , where A is a complex matrix, B is a complex vector and x is the vector of the unkown. The elements of the A matrix (that is simmetric) are in the form $A_{ij}e^{i phi_{ij}}$. I tried in several ways but I couldn't define the variables $A_{ij}$ and $ phi_{ij}$ as real. I tried using the package Algebra`ReIm` and to define each variable as z/:Im[z]=0. But it does not the wanted result and also I've already read the help page for ComplexExpand[]. Thank you, every suggestion will be helpful. Fortu
