Solve system of equations (nleqslv) only returns origin

You should return the vector y i.e. function values.
But y has length 4 and x has length 4.

So where is the fifth value for y?

  }

Xstart=c(10000, 200, 0.5, 0.5, 12)
fstart= firstordercond(Xstart)

If you print fstart you will see that it is identical to Xstart.

You need to rethink you firstordercond() function.
It's not correct.

nleqslv(Xstart, firstordercond)
