Hi, MathGroup,
FindMinimum[f, {x,x0},{y,y0}, ( ] searches for a local minimum in a function
of several variables, x0, y0,... are the starting values for the search.
How can I use FindMinimum without having to name the components. My f is already of the
form f[x_List] and I would like to start the search on a given starting vector. The result,
which one would normally obtain as
{x,y} /@ FindMinimum[f, {x,x0},{y,y0}, ( ][[2]] should be returned
as a vector.
The application is, when I have several minimizing problems with different number
of parameters. I have found a way to construct names for the variables
from strings using ToExpression, but I am looking for a more elegant
solution for this problem.
kind regards
