Have you tried writing a function to compute SS = sum of squares
deviations between the the left and right hand sides of your three
equations, then using 'optim'? See also Venables and Ripley (2002)

Hello,
The 'do.NULL=FALSE' option of 'rownames' and 'colnames' does not
work as documented when the array has a 0-extent dimension:
tmp - matrix(1:15, ncol=3, dimnames=list(letters[1:5], LETTERS[1:3]))
