This function determines values for `x`

, whence they have not
been specified by the user. Here, a feasibility problem is solved
first and its solution is then used as an initial point for the
original problem.

`SocpPhase1(f, A, b, N, control)`

f

`vector`

: the parameters of the objective function in
its primal form.

A

`matrix`

; the parameter matrix of the cone constraints.

b

`vector`

: the parameter vector of the cone constraints.

N

`vector`

: the count of rows pertinent to each cone constraint.

control

`list`

: the list of control parameters for SOCP.

A vector with the initial point for `x`

.

The finding of an initial point `x`

is described in the user's
guide, sectionb 2.8.
