I use Table[] together with FindRoot[] to repeatedly solve a system of
equations numerically. Now I would like to give the starting value for
the first calculation as prespecified while all subsequent starting
values should equal the n-1 th solution.
Here is a simple example, where the starting value is fixed for all
calculations to follow.
Clear[g1, g2]
g1 = a x + b y == c;
g2 = d x + e y == f;
Clear[a, b, c, d, e, f]
a = 0.5; b = 0.1; c = 2; d = 0.9; e = 1; f = .2;
Clear[a]
Table[FindRoot[{g1, g2}, {x, 4}, {y, -4}], {a, 0.5, 1, 0.1}]
