Problem solved.

Yes, least_squares can, of course, handle multi-dimensional situations.

Me burning midnight oil was the problem. I have been tinkering a
bit with scipy.optimize.least_squares tonight. All simple examples
I tried worked regardless of number of dimensions. I went back to
my old code and found a couple of basic mistakes. Done.
