Tool function to construct and find the solution of the minimization problem involving the quadratic form \(x'Qx + b'x\). Not an optimal one. You can provide one better then this.
ifsp.cf(Q,b)
the vector of the coefficients to be plugged into the IFS
the matrix \(Q\) of \(x'Qx + b'x\)
the vector \(b\) of \(x'Qx + b'x\)
