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.
