Q. A student aims to use Cramer’s rule to find a solution for a homogeneous system. But while finding the solution, he observes that he is getting infinity as a solution. The code is

p=X.\C

X is the matrix created by replacing a column with constant co-efficients in the equation.
C is the co-efficient matrix
P is one of the variables in the system

Is this a proper justification?
