Solve a system of equations.
This function takes a co-efficient matrix A and an output matrix B as inputs to solve the following equation for X
\(A * X = B\)
This operation can be done in ArrayFire using the following code snippet.
This function along with af::lu split up the task af::solve performs for square matrices.
