How to implement arg min f(x)?
Hi, I want to implement arg min f(x), but when I use the FindMinimum function it returns the minimum and it returns the argument for the minimum in the form "x -> 1.234", i.e. a string. I am using the minimization in a manner analogous to solving Ax=b for x by finding arg min ||Ax-b|| x How do I pick off the value of x? To further complicate things, I am using the Excel/Mathematica link package, and I want the value of x for use in Excel. Thoughts?
