As nearly as i can tell from Solver help, this is designed for scalar

targets. I'm looking to make an N-vector converge. I would much rather

do it in a program for matrix algebra, e.g. "R", which is freeware, but

there are others working with the same project that need to be able to

"see" how it is converging.

....

Depending on what sort of convergence you want to achieve, you could use a

scalar statistic based on your N objective functions. So if you want

(f(x,y,z),g(x,y,z),h(x,y,z))

to converge to (f0,g0,h0), you could try minimizing the scalar statistic

SUM((f(x,y,z)-f0)^2,(g(x,y,z)-g0)^2,(h(x,y,z)-h0)^2)

Difficult to be more precise without any details about what you're trying to

do.
